Al,  you  need  not  replace  the  HV  supply  cap,  unless you  know  it is 
  bad.  The  low B+  caps  I  think  are  40 ufd   and  the  bias
supply  caps.  Also  any  electrolytics  in  the  audio chain.  Just  these  
few  items  will bring  the  Viking II  back to  life.  The  hi
B+  cap  is  oil  filled  and  usually  is  good.  Unless  you  want  hi-fi  
audio,  that  should doit.  Look up  Antique  Electronic
Supply  in AZ.   Go  to www.tubesandmore.com      Enjoy  the  project-

Al, most people will tell you that Mouser has the best prices on components. However I order most of my parts from Antique Electronic Supply in Tempe Az.  I believe their website is,
www.tubesandmore.com  
I've restored 3 different radios recently and they've always had the parts I need.  Good luck with your project.

The Johnson Desk Kilowatt is fundamentally a good rig, with high grade 
components that opreate well within their maximum ratings.  Depending on 
what you drive it with, the audio can sound excellent.  However, I think the 
desk arrangement along with the horizontal front panel on the transmitter, 
and the funny little rotatable meters was a silly design.  I would much 
rather have the same circuit and components mounted in a conventional 
cabinet with a normal front panel in a vertical plane.  Imagine the 
fireworks inside a Desk KW when coffee or an 807 gets spilt on top of the 
"pedestal".

Speaking of meters, I hope the *first* thing every AMer does with a 'new'
rig is drop a diode or two across the meter posts. Happiness is never
having to ask: "do you have any spare meters?"

* Even before replacing that dual-fuse linecord.

Good morning all you fine hams out there.

I have an SX 28 that has suffered lightning damage to one of the input coils.  That is the kind that comes from the sky, not the white kind.   

Does anyone have a junker with a good T 10, the band 4 input coil.  If so, I am in need and would appreciate any help.

I'd recommend removing the coil and inspecting for damage. Often the
winding will fail outside the coil on one of the leads (hope, hope). Then
check each bundle for continuity. Then start unwinding that bundle until
you reach the break.

Brush on melted beeswax as you manually wind it back to full.

Also, you may find that a coil from almost any rig from that era,
especially one running the same tube, will be an equivalent substitute.

Before I follow my own advise above, does anyone have a junker GRR-5
(R-174) receiver?   ;-)

Someone asked for details, forcing my pen to paper, as it were.  ;)

The common, everyday silicon diode is in fact a 0.707v zener diode. Thus
if placed across those fragile and expensive panel meters on AM-CW rigs,
any input voltage will be clamped at that value, and no damage to the
meter movement will result. Since we do not know the polarity of any
insulting voltage, place a second diode the other way across the meter.
Use nice terminal connectors and solder so the protector will remain with
the meter forever.

Why should I care, you ask? If the meter switch gets dirty and your
precious meter is exposed to normal voltage, but without its proper shunt,
poof! That meter is now history and the begging and whining for a
replacement begins.

Schottky diodes provide even more protection, somewhere around 0.4 volts
(?). Sometimes this is a bit too much limiting as the meter does not do a
full swing. But you may need it to get better protection as a trade-off.

Hi!

A number of people have asked about the 400 watt MOSFET transmitter, so I'm
going to bring the 40 meter, 400 watt RF deck to Hosstraders (the one built

Come on by and check it out :-)

Hope to see lots of the AM folks there.  Weather forecast is real good for
Friday and the weekend :-)

Hi Bill,

I have a friend that reads this reflector and he told me a story about doing the bee's wax thing.  He had his wife holding the coil while he spilled melted bee's wax on her hand.  It was all he could do to keep her from throwing the coil across the room.  She held on and it was fixed.   

The real problem with the 28 is getting the old one out, which I will have to do in either case, but with a known good coil, I am more comfortable installing, as I am old and shakey especially winding coils.   

What a laugh I got from your message, thanks for breaking the monotony.  Hope Charlie doesn't mind me telling his story.

Hi Y'all,

Sometimes a 0.7 volt diode will still put too much voltage across a sensitive meter.  If you are dealing with a supply of 2 or 3 hundred volts, you will not miss a few volts so I put enough resistance in series with the meter to make sure the meter will not see more than about 125% of its maximum.  I usually use the lowest voltage zener I can get, probably 5.1 volts.

See:  http://www.zianet.com/wb5lhv/meter.jpg


73,

Charlie

    I have several boatanchors that need various amounts of repair and
restoration.  I am looking for suggestions on what materials to use for
cleaning rigs both inside and on the exterior.  Ideas on what to use or what
not to use would be helpful.  What about touching up paint chips, scuffs and
other marks?  I consider you guys the experts and I value your experience
and candid comments.  Thanks... Ron VE4SR

	Dan,

	I am the proud owner of two G-76's, and two home made power supplies, one
mobile, and one base. I am not looking to get rid of these rigs right now,
but have you checked ebay? I have seen several Gonset mobile supplies on
ebay the last 6 months. There was an AC supply as well. Keep looking!

Jim:
Thanks. Yes I try to keep in touch on Ebay. Are the various supplies
interchangeable from model to model?  The one I have seen with the G-76 has
a speaker and a cloth front and appears to "match" the transceiver.  I have
a Heathkit HP-23 for it now which supplies all the (close) voltages.

Thanks

While digging through some junk boxes I came across an old CB radio. I
haven't looked in one in a long time but remember that some had some
pretty nice ceramic AM filters in them. I think at 455 kc. Might make a
good AM filter for some of the old radios. May need a couple of matching

Trade unboxed for your similar 4-400A's or sealed boxed for your

Hi guys -

I'd like to sell my General Radio Impedance Bridge model 650-A.  It has the power supply and an oscillator built-in.  Physical condition is excellent (there are some scratches on the nameplate, otherwise pretty sharp).  It has been years since I last put it to work so I can't realy attest to its performance.

A photo is available online at:

I'm thinking $50 would be about right if we split the shipping.  

Anyone interested in this classic piece of test gear?

Thanks...

Gary,
Not sure how well the CB filters would work on tube gear.

Kiwa makes a very nice 455 kHz filter module available
in any bandwidth you want (I like 5.5 KHz).
It comes in a small encapsulated module you can Velcro
onto any handy spot.
It has an op amp input, three separate filters to give
the desired bandwidth, and an op amp output.
It runs off about 5 volts to 30 volts dc, and has no
loss through the filter.

It comes with pig tail shielded wires you just tack
onto the circuit.

It works amazingly well on my home brew receiver, allowing
good fidelity, and I can listen on 7290 without
interference from people operating on 7295, as long as
they don't splatter....even very strong signals don't
come through, as long as they are clean....

You can tack one of these things on any 455 kHz IF receiver and get
mechanical filter results.
All you would likely have to do is lift a couple of parts and 
tack the wires on....

Another thing I really like is the new freq counter/digital readout
kits you can get cheap.
They pick up the LO signal and offset 455 kHz to give a direct
digital readout of the received frequency.
You don't have to hook anything up to the classic
boat anchor receiver, just get a pickup wire close to the lo
tube.
AADE makes some very nice ones, and oak hills research sells
a kit with a cabinet...just put it on top of the receiver and
have an accurate readout.
Just the thing for my SX17...its dial is marked every
100 Kc!

I don't own stock in these companies, but I am hoping if I say nice
things about them, they will send me some free samples!

If it says 'Collins' be prepared for a royal hosing by SS. Figure out the
V/I requirements of that relay and run anywhere else: eBay
'components/parts', fleafests, local recycle flowstream, etc.

Thanx for the reminder to get one for my 32v3. Semper paratus.

Hey John,

I gather, like me, you didn't make Dayton this year, either.

The bands have been dead around here as well.
I have not had much time to play radio, but did manage to fix my
40 meter antenna that fell down....its a bit higher now,
so I expect a big 10DB of gain from the extra 4 feet!

Even when I hear someone on 40, they were weak...maybe
80 meters will be coming back during the day soon...

I suspect everyone is busy with yard work/house work/car work

Sunday I could just barely hear WWV on any frequency. 

The skywave on the AM band has been terrible, and the "A" index is holding up 
way too high. When it drops back down, at least the BC band will improve, and 
hopefully the other bands with it.

I've been collecting more 'spares' and 'collectible' transmitting tubes
off eBay. Often the seller offers a money-back guarantee of xx days if the
tube doesn't have ~full output. This is a kind gesture but raises a
problem of how to easily test these to see if they are at least in the
right ballpark. Opening up the big rig and removing shields to get at
perfectly good tubes seems pointless just to run tests on newcomers.

Has anyone seen a simple test setup to check cathode emission and element
shorts while tube is hot? I'm thinking of a variac controlled B+ of no
more than 800v for safety and simplicity. Would this give a good profile
of a particular tube? Would it be enough to expose gassiness? Perhaps
someone has seen an actual tube tester for power tubes or the schematic?

It would be fun to run off curves at this low voltage to compare to those
published by mfr.

Not sure how reliable this approach would be.... I have a few 4-400s that
work just fine at low power (1/2 normal HV, ~1600V on the anodes), but they
don't like full HV at all.

There was an article in one of the ham mags - or maybe a GE hamnote -
probably in the '50s, that described a test jig for TX tubes.  Basically an
oscillator arrangement. But I'm pretty sure it used close to nominal
voltages.  I filed my copy of it in a safe place - yes, gone forever.

I have the article of the GE publication and while it does give ideas of how
to test power tubes, the jigs look just as elaborate as the equipment in
which the tube would be used.  Given the fact that tube testing is at best a
test for shorts and emission, actual service is probably more realistic in
any event, and no doubt more so for power tubes.

Running tube characteristic curves does sound interesting, but think it
would take quite an elaborate high-voltage switching scheme, even if only
grid voltages were controlled.  I recall a unijunction based project I built
once from a Popular Electronics project to generate transistor
characteristic curves on a scope.  A pair of unijunctions were used, one as
an oscillator to generate a staircase, the other to periodically reset the
staircase to zero.  It was very simple and seemed to work quite well.  I
suppose that approach could be used, with DC amplifiers to increase the
voltages to be compatible with tube operation.

The best test is to put the tube in a class-C plate modulated f inal, 
running at about the maximum rated class-C telephony limit for the tube, and 
observe the trapezoid pattern on a scope for linearity.  If it will make 
100% or more positive without excessive curvature on the sides of the 
triangle,  the tube should be good for about any service you plan to use it 
in.

W5PYT Ozona Bob use to put 250ths in a 610 tune it up
and the throw it off resonance and see what it would
pull..I think he looked for 500 mils for a second or
so....It was only rated for 350ma so it would get
quite Red..He would pronounce it good...

Yup, I have done the same thing for many years. Once you know how much
current a good tube will draw off resonance it is a good indication of
how good the one under test is. It is quick to do. Just don't leave it
off resonance for more than the time it takes to read the meter.
I do this with 6146's when ever I put one in a boat anchor.

Hi Doug,

one of my reference books shows 5915, EK90, 6BY6, 5750...

I would opt to get the more common 6BE6... unless of course you
don't mind butchering the set... redesigning the whole works...
I've been there... not pretty...

Believe it or not I've got a copy of the GE Ham News article right here, and 
will put it on EBAY right away......only kidding, its May-June 1951 (V.6 No.3 
for you librarians).

It details 4 tests - continuity/short/static/14 mhz power oscillation/limited 
peak emission.

I don't think it will scan or copy well, (I made the copy 25 years ago) but 
I'm willing to make a copy (or try scanning) what I've got if you want to try 
it.

Bill,  these tubes  have  been  sitting around  in a box  for a  while.  So, 
  I  decided  to retest  them.  Using a  TV-7  tube  tester
they  are  all testing  weak,  including the  2  new ones!  I  have  nothing 
  to try them in,  so  I  cannot  be  sure of  their true
condition.  AES  wants $52.50 for them.  All I can say now  is  make
an offer.  If  you  decide not  to offer,  I  understand.  Russ

Here is some interesting stuff at these links:

This one is really cool to me.  It shows how the plate efficiency is
raised to 90% in the RCA High Efficiency Class C circuit.  So good did
it work, the plate dissipation was so low, that they only needed one
tube in the final to meet the plate dissipation needs, where as before
there was two. http://www.nrcdxas.org/articles/bta5t/

Hey Gang!

    The "Beast" is up and running!  Now I am in search of additional
components.

    1) A TU-52, 6.35 to 8.0 Mc.  (The one I have works, but an internal coil
looks to have been "cooked" in days gone by.  I don't know how long it will
last.

    2) All manner and sort of FT-171-B crystals.  I have about 8 or 9.
Those outside the ham bands are fine, if they are below the bands.  I'll
diligently and carefully do the tooth powder routine with a piece of plate
glass and tenderly bring them up to the needed frequency.

    3) A BX-34 FT-171-B crystal box.  Got to have some place to store these
monsters.

Thanks for reading!  And Thanks for your searches!

The 7360 makes a very nice mixer, probably better than any solid state 
design.  It has some gain, very low noise and spurious responses.  One 
problem is they have become rare and expensive.  An inexpensive alternative 
is a 6AR8, listed in the 2002 Antique Electronic Supply catalogue for $5.50. 
  The only drawback is that one of the grids is internally connected to one 
side of the filament, which would have to be grounded.  That shouldn't be 
too much of a problem if you run DC on the filament, which I would 
recommend.  I have built mixer circuits with these tubes, and they are very 
sensivive to stray magnetic fields, including that of their filament when it 
is powered by 6.3 vac.

The 7360 makes a good rx mixer as well as balanced modulator for anyone 
interested in homebrew slopbucket.  Would be curious what kind of results 
anyone has had with the 6AR8.

N2EY reports that 6JH8 or 6ME8 are supposedly preferable to the 6AR8.

I am currently working on a Valliant 1 I am trying to get on the air. There 
was a discussion (I'm pretty sure it was one of these reflectors) about using 
solid state devices for replacement of the 866 regulators. They are very 
pretty and all that, but really unreliable. I already had one short and had a 
big arc under the chassis before the fuse popped. Please some info on doing 
this. I had a problem also in that the dim past some one recapped this rig 
with higher than print specs caps. Called for 15ufd and they put in 22ufd. I 
believe this makes the pwr supply work harder. They also grounded one end of 
the caps, and grounded the center tap of the HF xfrmr. It appears when you 
measure this leg it IS ground, however the .202 ohm resistance for the plate 
meter is in there. REALLY hard to read. Any how that made the plate and mod 
meter inop. Fixed that up(have to order caps) but now cant get the plate to 
dip on 40 and lower. Also have too much plate current for drive. Have 
replaced finals and neutralized them. This helped too. Any thoughts on the se

Not quite the 866 function here.

Most likely NOT the fault of the 866's. Please unplug this rig now, and
revert to 'bench-mode'. Hate to see good iron get trashed as it is getting
scarce.

Hope you didn't fix it by bringing meter to B+ side!

Gee, a nice Heath Cheyenne just went for $43-US on eBay. Might be a better
starter rig.

Do you have an ARRL handbook ca 53 - 75? Online can't be a substitute for
the Handbook. You've gotta go back and forth section by section. Takes
time. Every point you raised here is a whole chapter in itself. Keep at it
and use the archives. And not every mod published is a good one, or a good
one for YOU. Doing mods/repairs without knowledge can be counter
productive. 

First get the power supply solid and complete. Solid state it if you want,
but this is not necessary for your first rig. 3B28's should be easy to
find and better behaved. Test the ps completely without any circuit
connected to it. Use a couple load resistors as a substitute for the V1
circuits. Then treat each section of the rig individually. Count on having
that rig up on end for months.

Good luck.

You didn't mention whether or not your rig was working properly when you
decided to solid state the HV supply.

When I got my Valiant, the 866 filament supply on the low voltage XFMR was
shorted so I was forced to solid state it or find a new transformer.

I made 2 stacks of 1N-5408 diodes (1000 V PIV) and did the mod.  I used the
866 tube socket pins as tie points and removed the filament supply leads
from the socket and insulated the cutoff wire tips.  The rig came up fine
but the final plate voltage was about 760 volts (50 volts higher than
design).  I ran it that way for a while and then decided to lower the
voltage by putting 10 watt 50 ohm wirewound resistors in series bfore the
input to the choke filter circuit.  This had been suggested by a mod article
on the web. I never remeasured the voltage to see how much that had lowered
it because I fried my ohmeter tryin to do the measurement.

If you installed the diodes correctly and they were beefy enough to handle
the voltage and current of the circuit they shoulduld be OK.  The increased
voltage produced by the mod may have broken down one of the capacitors in
the output arm of the filter (C91 or C92) or some other component.

If the fillter capacitors are old, I would replace every electrolytic cap in
all the supplies to start.

You are having problems on the lower bands which suggest that you may have
one or more bad contacts on the wafer of the Auxiliary Coupling switch.
This can blow fuses. take a good look both sides of that wafer.  Clean it up
with De-Oxit.   Check the 2 mica capacitor networks which hang from the back
wafer of the band switch.  They are part of the PI network input.  If you
have loading problems because of a bad antenna coupling switch or bad
loading capacitors - some of those micas will fail dramatically blowing
sparks and flames from their sides.

Hope these suggestions are helpful to you.

73 and gud luck,

Did you try clicking on the mailman-listinfo-amradio URL at
the bottom of the AM List messages, then at the bottom of
the screen you get, enter your e-mail address to cancel your

AL,
866's are rectifier tubes, not regulators.  They require a little care in 
their use, but are generally reliable.  They must be aged in when first 
installed without HV on them, then they must be carefully pre heated each 
time you light up the transmitter, before applying HV.  Also, mercury vapor 
tubes are sensitive to mounting position. Operating them with the transmitter 
in a non standard position, may allow the filament to sag and cause the 
result you experienced.  Putting B+ on them cold can also blow them up. 
Download a data sheet and get familiar with what you've got there before you 
light it up again.  3B28s are a non mercury vapor tube that can usually be 
plugged into the same socket and don't require quite so much skill in their 
use.  But you have to find out what took out the 866 before you put anything 
else in there. Was it operating conditions or a problem in the load on the 
rectifiers? You could have a choke that is arcing, or a filter capacitor 
shorting. You will just be blowing up solid state diodes or 3B28s instead of 
866s.  The 866 is a rugged reliable tube when used properly and it should not 
have shorted just because it was having a bad day.
    It seems like you are having a lot of trouble in other sections of the 
transmitter.  Try to make sure the power supply is solid as a stand alone 
unit, filter caps, good, etc.  Then troubleshoot the transmitter section by 
section, perhaps at lower plate voltage using another power supply.  
Otherwise, you can go through a lot of difficult to locate and replace 
classic radio parts.

Alas, I don't think there's a better way than rotating thru new email accounts
periodically.
Hotmail and other big hosts are the worst since they are targeted more than
others, but everyone is susceptible once you let that address out into the big
bad world, especially on listservs.  I've had a few others and they get spammed
pretty quick once you get on any lists.  Juno was unbe-LIEV-able!

Still waiting for the email 'killer app' that can deal with this effectively.

Meantime, wearing out that delete key...,

I am using a program called MailWasher which I downloaded.   I liked it so
much that I payed for a subscription.
It downloads email headers form your mail server and checks the content
against online spam databases.  It then lists the messages, highlights
suspected spam and gives you options to delete or bounce the messages
without downloading them.  You can preview a message which downloads it to a
local buffer without triggering your email reader if you want to see what
the contents are before making a decision. It allows you to form a personal
blacklist of senders or domains.  You can override external or local
blacklists for individual origins and senders with a mouseclick and the
program saves the updated screening logic.
My spam has decreased significantly and I look forward now to screening and
bouncing the garbage back to the SOBs and their internet providers.
A Google websearch will get you the latest version.
See what you think.
There are other spam-blockers out there as well.  You might find something
better but I am satisfied with this so far.
I did preview a message containing a virus and the Norton's Antivirus
"attack screen" came up saying that my computer was being shut down to
protect it.  When I rebooted I a complete antivirus screen of all my
hard-drive files and then deleted the virus containing message from my
mailserver using MailWasher without downloading it in Outlook Express.
