As a reminder:

OMARC is the host on the TIROS site during the Vintage Computer Fair.
We will be on site both Saturday and Sunday, so if you are available and
want to meet some of the folks who are preserving our computing
history, this is your chance.

As an added bonus, The team is putting the TLM-18 on the air (on the
moon) on Saturday, April 16th, 2016. Moonrise is about 14:30 local, so
if you want to try EME, here's your chance!

Folks,

The Radio Technology Museum <http://www.rtm.ar88.net/>, located at the 
site of Marconi's Transatlantic receiver site near Belmar, NJ, enjoys a 
close relationship to our hero Edwin Howard Armstrong.  This was the 
site of Armstrong's demonstration of his regenerative receiver to David 
Sarnoff in January 1914.

Over the last couple of years we've created a fair amount of Armstrong 
material, including some interesting video demonstrations.  (Have you 
ever heard a spark radio-telegraph signal on a regenerative receiver?)

Take a look here:  http://www.ar88.net/arm4/home/default.html

Enjoy,
Al

Thanks Al,

    I passed this onto my local Ham club here in Maine  http://www.penbayarc.org/  Like other Ham clubs, we have people with varied interests up here.  There's not a lot of interest in the older equipment, but there is interest just the same.  I feel like Johnny Appleseed sowing Radio interest seedlings.  
    We'll see what sprouts.

Neat video but sounded like the Crosley was in need of filter caps!
Surprised that the owner would let it run in that condition.  The Zenith
Strat sounded cleaner.  Thanks for passing along the video.

All,

Here's a long shot, but worth an ask. Does anybody know what the electrical terminals attached to the resistors in the attached picture on the plastic piece are called and or where I can get them? They look like spade crimp terminals, but they have little loops to hold the resistors in place.

The ones on my pack are super rusty, and do not want to come clean using Evaporust or the fiberglass pen\file.

I've went to the usual car parts stores and home improvement stores and I'm coming up empty handed.  If anybody can spare some that'd be awesome too.

Thanks!

I presume wen you say pac you mean packard. If so did you try J C Whitney, I think they are still around. There are probely other places if you get on lime.

  All,

  Here's a long shot, but worth an ask. Does anybody know what the electrical terminals attached to the resistors in the attached picture on the plastic piece are called and or where I can get them? They look like spade crimp terminals, but they have little loops to hold the resistors in place.

  The ones on my pack are super rusty, and do not want to come clean using Evaporust or the fiberglass pen\file.

  I've went to the usual car parts stores and home improvement stores and I'm coming up empty handed.  If anybody can spare some that'd be awesome too.

  Thanks!

Ah, I recognize them - blower motor resistors for you DeLorean.

I assume you want the connectors for the ends of the wiring harness.  
Don't know what you mean by "...little loops to hold the resistors in 
place."  The resistors are the coils, very low resistance.

Normally it's one multi-contact connector.  Looks like you can use 
individual normal 1/4 inch slip on crimp connectors.  like these,.  I 
have some insulated ones, but you'll need to pull off the insulator .  
They'll take 12 thru 8 ga wire.  I also have the next smaller size, 
16-12 ga.

I can bring some tomorrow if you like, or just pick up some at the blue 
store or orange store.

Thanks,
Bill

All,

Let me clarify a bit.  First, Bill was right, it's my blower motor resistor assembly for my car.  Second by pack I meant the entire assembly.


The part I meant that I was hoping to replace was the clips that are holding those resistor coils to the plastic tray on the bottom.  If you look at the terminal from the point where the coils attach to them they look sort of like the spade crimp terminal that Bill pasted in his reply, but there are loops on the "female" side that hold the resistors in place.  It's not the same spot that normally holds the male spade in place.  I have normal spade crimps I could make work like Bill suggested, but just curious if that part was a known off the shelf part or some custom made connector.  I know so many of us have vast junk drawers of parts.


I hope that clarifies.  thanks for the opinions and assistance thus far.


Regards,

Matt

Matt,

First off, I assume the nice, clean resistor pac's in the picture are 
not the ones you're trying to rehab.

Connectors of that type are called Amp Fast-ons.  the company has 
morphed into TE Connectivity.
The whole catalog is HERE 
<https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0ahUKEwi1ovvx5P3LAhWM7RQKHU9VCe0QFggjMAE&url=http%3A%2F%2Fwww.te.com%2Fcommerce%2FDocumentDelivery%2FDDEController%3FAction%3Dsrchrtrv%26DocNm%3D82004_FASTON_TERMINALS_-_FULL_CATALOG%26DocType%3DCS%26DocLang%3DEN&usg=AFQjCNG7OzlL_CFOgFRXaQHZQZ-O4k3jAg&sig2=odvQBM2QwTw6WOr1PjEw1A>. 


Scroll down to "tabs."  Unfortunately the ones you have are probably 
custom made, and if you replace them there may be a problem making 
proper connections yo the resistance wire.  Is the problem dirty tabs, 
or is it bad crimp connection to the resistance elements?

My two cents,
Al

Al,

Thanks for the details.  I'll check out the link. 

Yes, the shiny clean ones are not mine.  I'll take a picture (or bring the actual one tomorrow).  I could just replace it, but it's one of those things that costs little but shipping would be high, and I don't need anything else to order from the parts suppliers right now.

The crimps are fine, everything is nice and tight, it's just heavily rusted\corroded on the resistor side.  The terminal side for the other connection is not very clean either, but with the fiberglass pen I was able to get a shiny finish (took off some of the plating).

The fiberglass pen just keeps cracking away on the strands because it's not a flat surface.  will try a brass wire brush or something.  Sort of afraid to disassemble it because i don't want to stretch out\loosen the connections unless i had something to replace if I broke them.

Thanks all for the lively discussion.  Gotta love Lucas electrics...

Regards,

Matt

I replaced mine (the complete assembly) on my 1968 Pontiac Tempest many, 
many years ago.  The resistors are mounted in the plenum so they're 
cooled by the moving air (I guess heated air is better than no air 
circulation).  They get very hot, so re-mounting them on another 
substrate (big word-eh) might not be feasible.

I'm assuming you tried a GM dealer.

Yeah, I know how they are mounted.  the entire plenum assembly where the heater core and air conditioner condenser are sitting on my living room floor right now...  just finished refurbishing it.

I can replace the unit if necessary, they are still available.  This was just one of those things I figured "oh these should be easy to find..." and was quickly proven wrong.

Live and learn...

Hi Matt,
I had a very similar device in my 57 Chevy way back in the day. It is a 
blower motor speed control.
Not the safest device in the world either. When you switch to the slower 
motor speeds, those coils get hotter than a cigarette lighter. - lol...

Alex,

Thank you.  In case people don't look at the
entire paper, here is probably the major
point that the author makes:

"... It would be magical if cryogenic treatment were some kind of 
?cure-all? that improves the insulation properties of mica spacers, 
reduces inter-electrode movement and improves the emission of the 
cathode coatings to reduce noise and microphony. But I cannot imagine 
how this works ? ?magical? really is the right word to use here because 
cryogenic treatment of tubes is certainly not science. ..."

                                      Harry K

Hi Everyone 

I know we are a radio club, but all of us also own computers and I just wanted to alert you to something to avoid a nasty surprise. 

This morning I got a call from a friend in California whose Windows 7 machine had changed overnight to Windows 10. Now this friend is very computer illiterate and only uses the machine for email, so you can imagine how lost she was.  I had to do quite a bit of work over TeamViewer to bring her machine back to something she could work with. 

I did not have this problem since I have "automatically install updates" off in my Windows 8 machine. 

If you don't, however, be on the lookout for update KB 3035583. This update will automatically bring your machine up to Windows 10. I hope it's not too late to warn you, and you might be wanting the upgrade, but I personally think this is a bad way for a company to do business. 

I looked online for other complaints and saw a doctor who had to put off a test for one of his patients due to an unwanted upgrade at the wrong time. 

Also, before you contact a lawyer over this, be aware that right in the EULA, the agreement that you acquiesced to when you installed Windows, Microsoft has the RIGHT to do just what they did. Very nice. 

Best wishes and good luck. 
Bob

And even better, in Windows 10, you CANNOT disable automatic updates

Is this really the place to exercise a grudge against MS? ?I've voluntarily installed Win 10 and have had no problems.
Updates are fine for almost everyone. Confidentiality can be protected by a number of programs if that's the perceived problem. ?I definitely do not want to start a fire here but just noting that I, personally, don't find any issue and urge that this be moved to an appropriate forum.

Windows 10 is nowhere near as bad as 8, and Classic Shell makes up for the rest

Apparently you can. There is info on the web that says how. I have not researched it myself. 
Best wishes.

I'm sorry, but I did not intend my email to be a grudge against Microsoft but a warning to those who were unaware. I did not think that this issue should be a surprise. 
Best wishes.

Leo Larporte (techguylabs.com) has been addressing this issue for 
months. He has stated that one should keep up-to-date backups if you're 
going to upgrade to Win 10 in case something goes wrong and you aren't 
able to recover your Win 7 or 8 OS and personal files.

He's also mentioned Steve Gibson's registry hack to prevent the 
"automatic" upgrade. The best pre-upgrade advice is, backup, backup, 
backup...

Here's a site with info about permanently preventing the upgrade:

Thank you Louis. The site you sent me to talked about the program Never10. I downloaded it and discovered that Microsoft had surreptitiously installed 7 gigs of files on my machine in anticipation of the upgrade. The program allowed me to remove all the files. 
Thanks again. 
Best wishes. 
Bob

Subject: [NJARC] Selenium Rectifier replacement
Message-ID: <1541246b9c7-55f8-6226@webprd-m93.mail.aol.com>

Recently, I've come across a few 50's vintage radios that should have their selenium rectifiers replaced.  I'm thinking safety first over authenticity.  This is uncharted territory for me.  What are some of the guidelines to follow for their replacement.  I have some 1N4007 diodes, but I'm not sure of the math to follow.  When it comes to the corresponding resistor, is it best to use a 10 w resistor after you figure out the necessary resistance.

I don't recall seeing an article in our newsletter over the last 15 years or so. 

Thanks in advance for your help.

Subject: [NJARC] Super long shot - anyone have a schematic for a Panasonic
 RC-6900 talking alarm clock?
Message-ID: <BY1PR10MB03928FDE5898405D70BA5E0FB5970@BY1PR10MB0392.namprd10.prod.outlook.com>

Was a gift from a fellow member, works but needs filter caps.  I don't think i'll have a problem finding replacements (I have tons...) but just want to know what all the "other stuff" does in case I damage it trying to replace the electrolytics.  There are several.


It's a really neat device, and it still talks, but the amp\radio sounds terrible right now.


I already reached out to Panasonic customer service and as expected they didn't have anything.  I checked the online Sam's database and I don't think one was ever written for it.


And for those that gave advice on my blower motor resistor pack - thanks.  I was able to restore the terminals using a brass wire wheel in my dremel.  Worked much better than the fiberglass pen and  burnishing file I was using.  Soaking the connector side in CLR and then spraying clean with De-oxit worked very well on the plug side as well.


Regards,


Matt

JoeI personally think the issue of adding a resistor in series with a silicon diode to make up for the "voltage drop" of a selenium stack is just a waste of time. ?Another five volts should not make any difference at all as long as you don't end up over volting the electrolytic filter capacitor. ?More important would be to insure that the tube filaments were operating at or below rated voltage. ?This will at least guarantee longer tube life.?As an experiment, when you do the swap, could you measure the current draw of the radio and the B+ voltage with the series resistor in circuit and then with the added resistor shorted? ?
If you think about it, adding a resistance in series with the rectifier makes B+ voltage regulation in the radio worse. ?In other words, at volume peaks, the B+ voltage should droop a bit more with the resistor in circuit and less so when out of circuit. ?Current draw should not change at all since most of the tubes in the AA5 are pentodes where plate current is less affected by plate voltage.

Interesting to note that the resistor used in series with the selenium rectifier was there to limit peak current and to act as a fuse in case of selenium rectifier failure! ?Selenium stacks were crappy rectifiers; working on the edge of performance because they were limited by how much current they could pass. ?But they were more efficient then a tube rectifier and soon replaced by silicon diodes. ?

I have often heard people recommend that the resistor be added, to reduce
the voltage and also to limit inrush current through the new diode.  But
I'm not the engineer here, so I don't know how much validity there is to
their fear of the diode popping.  I'm gonna keep your experiment in mind
for the next time I find myself in that situation.

The predominant failure modes for silicon diodes are: 1. Overheating the
junction by gross current overloads and 2: Exceeding the peak inverse
voltage (PIV) rating.  Silicon diodes with 10 times the expected current
rating and several times the PIV cost pennies so they will be the last to
fail.

   I'm probably the least knowledgeable\qualified person on this thread thus far when it comes to radio repair but I was always under the impression the resistor was added to the diode to help account for the differences in how the selenium rectifier works\"acts" in relation to the silicon diode replacement.  It was my understanding the resistor was not added to protect the diode, but the resistor was to protect "the radio" from being "harmed" by the different characteristics of the silicon replacement.  I don't ever think I've heard of fear of the modern part being damaged/burnt out.

You should put a resistor in series with the silicon diode as the B+ will be higher when replacing the selenium diode.

SalSure, B+ will be higher but we are talking about an increase of FIVE volts typically for a Selenium stack rated for 130 volts @ 65 mA!?
(See?http://www.tubebooks.org/Books/srhbst.pdf?for the Sarkes Tarzian Selinum Selenium Rectifier Handbook, page 6)?Surely, a AA5 radio can operate reliably and tolerate such abuse? grin!
As Ray said. silicon diodes like the 1N4007 can survive non-repetitive peak currents of up to 30 amps versus 0.65 amps peak for the typical Selenium stack rated at 0.065 mA continuous current used in the typical AA5 radio.Jim

I replaced a selenium rectifier in a TO with a 1N4007 and had to increase the series resistor from 20 ohms to 47.  The series filaments are fed from the rectified DC, and the 1 volt tubes needed the additional resistance get them to the normal 1.3 volts.  So yes the resistor is necessary.

 Thanks everybody for your suggestions, comments and help.  I'll let you know how things go when I get it finished.  BTW... if you're interested in which radio it is, it's an RCA Model 6-XF-9J with a Gray cabinet.  Everything is original so at least I don't have to retrace someone else's work.  I just hope the IF cans aren't diseased.
I have the Beitman's sheets.  If anyone has a Sams or Riders, I'd appreciate having a copy.

Thanks again.

Joe



This is a photo I found.  My cabinet needs the Novus treatment.

Which Transoceanic? ?I checked the G500 and H500 schematics, which appear to be identical with respect to power supply, but didn't see a 20 ohm resistor associated with the Selenium rectifier.

I see your point though, the TO is a much different radio then the AA5 AC/DC radios which I was initially referencing. ?Looking at the "H500 Restoration Guide" (?http://www.renovatedradios.com/articlePages/H500%20Restoration%20Guide.pdf?), John Kopp suggests, among other ideas, adding a 9.1 volt Zener from the junction of R23 and S3 to B- so that the filament string never sees anything above 9.1 volts when operated from the AC line. ?
The Zener diode was added after John had already replaced R21, R22 and R23 in, what seems to me, to be an unfocused attempt to set the filament voltage across each tube to 1.3 volts. ?He seemed to have replace those resistors because they were out of tolerance but nonetheless changed the resistor values from those specified by Zenith. ?
Interesting to note that the 9.1 volt Zener will allow about 1.5 volts across each filament section at a filament current of 50 mA. ?But that said, the Zener diode is much saver option then adding a few ohms to the 2k or so ohms already in the power rectifier circuit. ?This in an attempt to drop the B+ supply a bit when changing from Selenium to Silicon to power the filament string when operating from the AC line.
Again, the filament voltage is much more important to tube life than a somewhat higher B+, (see http://www.bext.com/eimac2.gif?) ?note that this graph is for power tubes but it is still applicable. ?It would be prudent to also add a 24 ohm, 1/4 watt resistor between S3 pin 5 and the junction of R19 and pin 7 of the 3V4. ?This would drop about 1.2 volts and bring the filament string voltage to about 1.3 volts across each tube, assuming equal voltage drop across each tube filament section. ?This will be helpful whether operating from AC line or 9 volt battery. ?A lot less work and a better outcome then changing all of those power resistors willy-nilly.Jim

I replaced a selenium rectifier in a TO with a 1N4007 and had to increase the series resistor from 20 ohms to 47.? The series filaments are fed from the rectified DC, and the 1 volt tubes needed the additional resistance get them to the normal 1.3 volts.? So yes the resistor is necessary.

You should put a resistor in series with the silicon diode as the B+ will be higher when replacing the selenium diode.

?? I'm probably the least knowledgeable\qualified person on this thread thus far when it comes to radio repair but I was always under the impression the resistor was added to the diode to help account for the differences in how the selenium rectifier works\"acts" in relation to the silicon diode replacement.? It was my understanding the resistor was not added to protect the diode, but the resistor was to protect "the radio" from being "harmed" by the different characteristics of the silicon replacement.? I don't ever think I've heard of fear of the modern part being damaged/burnt out.

The predominant failure modes for silicon diodes are: 1. Overheating the
junction by gross current overloads and 2: Exceeding the peak inverse
voltage (PIV) rating.? Silicon diodes with 10 times the expected current
rating and several times the PIV cost pennies so they will be the last to
fail.

When you replace the selenium rectifier in a trans oceanic, there was
usually a 130 ohm 3 watt resistor in line to drop the voltage. Regardless of
which type of diode you change to, the focus needs to be on the filament
string or "A" voltage. Zenith specification was not exceed 8.4 volts. You
may want to install a 1R5 installed in the socket of the 1L6 unless you have
a bunch of them or "Bill Gates" funding. I've used varying resistances of
3-5 watt resistors for the drop after replacement.

BobOK, how does one not exceed 8.4 volts applied to the tube filaments when the TO battery pack has an A battery value of 9 volts (or higher when the battery pack was brand spanking new)?
Getting back to the original discussion, adding another 25 to 50 ohms to make up for the Selenium stack internal resistance does not significantly change B+ voltage. ?In the TO, that 25 to 50 ohms is in well within the tolerance of the 2000 or so total ohms that drop the B+ to the A+ level needed for the TO tube filaments. ?
Actually the three resistors in the filament circuit are 130 ohms (10%) + 950 ohms + 950 ohms (unknown tolerance) for a total of 2030 ohms give or take. ?So the internal resistance of the Selenium stack is about 2% of the total dropping resistance at face value without considering resistor tolerance.
Adding that little bit of resistance might work for one specific line voltage but there is no guarantee that the line voltage won't vary day to day or hour to hour. ?So what does one do then?
Funny, as you imply, NOS 1L6's are worth much more than a TO in average condition!Jim

Jules,

The attached diagram (modified in red from my microphone) presentation 
_should_ work.

For the transformer use an output transformer with a tapped secondary, 
preferably 8 ohms, tapped at 4.  Try 3 volts (polarity not important) in 
series with a 47 ohm (I estimate) resistor to limit current.

The connections are two the two screws on either side of the mic in the 
center.

This is all theoretical, but should work.  I'll try it myself tomorrow 
afternoon and let you know how it works.

With this circuit, the output will be very high compared to a normal 
microphone (hundreds of times), so connect it after any 
pre-amplification stages or use a pot to adjust/attenuate the signal, or 
try a single battery.

Now the legal stuff:
/"I shall not be held liable for any real or perceived damages or 
injury, direct or consequential, resulting from the use or installation 
of above circuit.  Your mileage may vary, close cover before striking."

Bill/

Jim -
        I think Zenith may have been concerned with varying amounts of house
voltage and current (my guess) because if you look at a schematic for a
miniature tubed T.O., some noted the voltage after the rectifier was 105
volts. Next the 130 resistor drops it more. Then if you really wanted to get
weird, zenith would use that .047uf bumblebee cap (that I've seen blow up)
beyond that. I've done at least a dozen or more of these radios and I think
that only once there was a problem with the multi-section 950 ohm resistor
riveted to the chassis. Yeah the battery new will reach 9 volts, but
remember a battery will not have severe possible voltage spikes like when
using home power. I have a homebrew battery pack I made several years ago
and I use 6 "D" for the "A" or 9 volts, and 60 "AA" batteries for the "B"
side. I usually use used flashlight batteries so I'm maybe between 8.4 and 9
volts. It will run any of my T.O's conservatively 40-45 hours before the "A"
side gets down to around 7.2-7.4 volts. There's a seller on eBay that makes
a power pack to run your T.O off DC, rather than using what came from zenith
but never tried one (I'm too cheap).

OK, egg on my face.  It wasn't a TO, it was a Hallicrafters S-72, kinda 
sorta like a TO.

I had restored the S-72 last month, then worked on a H500 that I had 
purchased for myself.  Old age being what it is, I said TO when I meant 
the Hallicrafters S-72.  BUT THE REST OF THE STORY IS TRUE!

Realizing that the 1 volt tubes were very fragile to higher filament 
voltages, I used that as a gauge to determine the correct resistor 
value.  I used 1.3 volts, as that's listed as the normal operating 
voltage for these tubes.  Surprisingly the voltages were not all equal, 
but off by a few hundredths of a volt, I guess to to slight variations 
in filament resistances (never would have noticed it with an analog 
meter).  The B+ did drop a few volts, but operation wasn't affected (I 
didn't document it, but it was still well within 10% of specifications).

Sorry for any mental anguish that I may have caused.

Gee, it's 9:15 AM already, time for my nap.

BillNot a problem and no need for the mea culpa, we are a friendly bunch here and all opinions are welcome; not one of us here is above impertfection!
We both agree, the most important thing is is to protect the tube filaments from over voltage. ?We just differ on how to do it and that is OK. ?
Selecting a resistor to make up for the higher voltage drop of Selenium makes little sense to me. ?Using a Zener diode to limit how high a voltage that can be applied to a series string of filaments is, for me, the way to go. ?This way, the tube filaments are protected for all line voltages. ?As for higher B+, the few added volts you get by going to silicon diodes is just a tempest in a teapot.
Now on to other things,Jim

   I replaced a selenium rectifier in a TO with a  1N4007 and had to increase the series resistor from 20 ohms to  47.? The series filaments are fed from the rectified DC, and  the 1 volt tubes needed the additional resistance get them to the normal 1.3 volts.? So yes the resistor is necessary.

   You should put a resistor in series with the silicon diode as the B+ will be higher when replacing the  selenium diode.

 ?? I'm probably the least knowledgeable\qualified  person on this thread thus far when it comes to radio repair but I was always under the impression the  resistor was added to the diode to help account for the  differences in how the selenium rectifier works\"acts" in relation to the silicon diode  replacement.? It was my understanding the resistor was not added  to protect the diode, but the resistor was to protect "the radio" from being "harmed" by the different  characteristics of the silicon replacement.? I don't ever think I've heard of fear of  the modern part being damaged/burnt out.

 The predominant failure modes for  silicon diodes are: 1. Overheating the
 junction by gross current overloads and  2: Exceeding the peak inverse
 voltage (PIV) rating.? Silicon diodes with 10 times the expected  current
 rating and several times the PIV cost  pennies so they will be the last to
 fail.

Jules,

Tried this with my mic with no results.  However, I think the problem is 
with my microphone.

It's an Electro-Voice Model 50 which was made in the 1920s.  It's been 
packed away, with the intention of displaying it , not using it.  
However, I thought this would be a neat experiment.

Getting about 25K ohms on one side and infinity on the other was a 
definite indication of something amiss.  I gingerly dis-assembled it, 
and found the carbon granules burnt, probably from too much current.  At 
least it looks as though it was used at one time. Interesting to imagine 
when and what it was used for.

I just found the attached on the web, an old EV catalog page, which 
shows this mike using 3-5 ma. for close talking, 10-15 ma. for normal.  
This would help determining the ideal voltage and resistor value.



I may have another double button carbon mic packed away, and I'll look 
for it soon.

Let me know if Mr. Hausler has any success.

Thanks,
Bill

Tim is a respected television restorer and collector here in New Jersey.
Although we don't see him at New Jersey Antique Radio Club meetings, he
does attend the Early Television Convention.

The Westminster set he'll be displaying at this event is almost certainly
the one he just finished restoring for Adam Sayles, the same fellow who
donated the RCA projection TV to our museum. As with our RCA, Adam arranged
to have the DuMont restored prior to his donating it to a museum.

Dear Mr. Dilks


Over the years I have been searching for a particular piece of RCA audio
test equipment which I would be able to use for troubleshooting audio
equipment at the choir's various concerts around our state of New South
Wales and also for use in my teaching classroom and repair workshop.

 
To date I have not been able to locate a second hand example of this RCA
Audio Chanalyst type number 170-A (see attachment) which I might purchase,
the only examples being those held by a couple of vintage radio equipment
museums which are not for sale.

 
However I have managed to purchase a complete manual on this piece of test
equipment manufactured by RCA Victor in Camden in 1945 and several of the
original John F. Rider and later RCA Chanalysts and

 
Yours Sincerely

 John W. Ward B. Eng. And Diploma Electronic Engineering (yes - I did my
university training at night whilst working in MANY roles in an electronics
company similar to RCA during the day over some six years -many, many years

Message-ID: <014d01d19eff$be259c40$3a70d4c0$@verizon.net>

Members and Friends:

Our big auction is this Saturday so this week is crunch time!  Here is the
plan.  

Wednesday and maybe Thursday we have to move all the goods from several
locations at InfoAge to the auction area 9032A.  A bunch of you have signed
up to help in this task so try to be at InfoAge around 10 AM Wednesday.  If
you have a pick-up truck , van, SUV or station wagon that will be a help.
If you get to InfoAge and you do not know where to go just call my cell:
908-472-3329.  InfoAge will also provide help.  There are 340 lots to move
from one of the back H buildings and other places but if we have enough help
we can do it in one day.  If not, some of us will have to come back
Thursday.

On Saturday, Marsha, Edith and Dave Snellman will handle the check-in and
check-out office.  Steve Rosenfeld and Aaron have volunteered for auction
clerking.  I'll need a half dozen runners throughout the auction.  Also
someone should be on site at 7 AM to direct parking.  I plan to be there
before 7 AM.  We will be open for viewing at 8 AM, the auction starts at 10
AM and continues without pause until all items are sold;  estimate by 2 PM
or so.  I also need a couple of volunteers to guard the large quantity of
tubes from 8 AM till auction time.

Food will be set up in 9032A at about 7:30 AM by the Country Kitchen.  They
have good food, patronize them, they will have breakfast items as well as
other food throughout the day.

I will hand out instructions to runners on Saturday morning.  Runners and
all other auction workers are free to bid on any items offered.

Cledis and John Estes are the auctioneers and they come from Ohio to
volunteer their services which is much appreciated, be sure to thank them.

Any questions call me at 908-472-3329.  Visit auction at ar88.net
<mailto:auction at ar88.net>  if you have not done so already, most information
is there.

Have fun, Ray

Message-ID: <571FEF36.8000600@poetworld.net>

Need help in valuation.

This speaker, images attached, was donated to a nonprofit charity for 
resale to raise funds.  Because it is known that I am an NJARC member I 
was asked to help in valuing this speaker, as if I know anything about 
1920's loudspeakers.  Anyway, would some kind soul venture to say what 
magnitude of funds this item might generate?  In other words, what would 
this variously would sell for at a typical NJARC swapmeet, or at an 
auction with bidders who know what they are about, or say, flea market 
or rummage sale price, Craig's list, or even (ugh) Ebay?

The speaker appears to be in very good original condition, no tears, 
holes, massive corrosion, etc. but neither does it look showroom new. 
It seems to work to the extent that a C cell causes it to make scratchy 
sounds, further testing was not done.

Any help would be much appreciated.

Although not specifically about communications receivers, this newspaper story has some nice photos of a radio repair shop that has been in operation since 1931 and is still in operation today.  

Be sure and click on the slideshow button on the photo at the top of the story to see the other photos of the current repair area along with some older shots.  

It looks like a pleasantly cluttered shop where one could enjoy a conversation with the owner:

Members and Friends:

Thanks to a great turnout yesterday with willing hands (and no injuries) all
340 auction lots were collected up in record time and set up in 9032A for
the Saturday auction.  You totally blew my estimate of the magnitude of the
task and did in a little over two hours what I thought might take four times
as long, a great effort much appreciated.  I hope to see most of you on
Saturday as runners and monitors.  John Kaminsky has volunteered to be a
guard over the many vacuum tubes and he could use some help.  Viewing starts
at 8 AM, the auction at 10 AM.  During the viewing period I hope all
volunteers will be on the lookout for anyone trying to start their
collection ahead of time.  I will have instructions for runners.  Runners
and any volunteers can bid on items as long as you have a bid card.
Volunteers please wear your club shirt or an InfoAge shirt so you can be an
ambassador for the club.  I still am looking for someone to help with
parking cars from 7:30 on  for an hour of two, any takers.

Thanks and have fun, Ray
