[Snowball] Heads Up Al

Greetings fellow snow warriers

Walked down to the PO (about a quarter mile) yesterday (Friday) to get the 
mail.  I was expectecting a small box/envelope of parts from an ebay 
purchase I made in late December that is coming from Thailand.  So, I was 
happy to see the call slip in my box.  But when I got to the window, Post 
Mistress Peggy said "You'll have to come in here -- I'm not going to pick 
that thing up off the floor!."  I had given up on ever seeing the snowball 
so all I could think was "That's way more than what I ordered!"  After 
staring at it on the floor for a couple seconds, I mumbled "Huh?"  I could 
see fear in Peggy's eyes -- she was afraid that I was going to stick her 
with the monster!  Finally I recognized Bill's name on the label and it 
struck me... splat! <g>.

Timing was great -- I have been out of town for a few weeks and my neighbor 
who picks up my mail would have had a problem with the box.  Are you sure 
it's only 31 lbs Bill?  It seemed a lot heavier after I got it up off of 
Peggy's floor and huff-n-puffed it back up the canyon to the house.  (I knew 
Peggy didn't want me to leave it there while I went to get my pickup)

Opened the box this morning.  Pickin's seemed a little slim (compared to 
Lloyd's original snowball) which made me sad and happy at the same time. 
Sad because I missed some of the excitement of examining all the exotic 
goodies,  happy because I knew some people who don't have 20 or 30 40 or 50 
years of accumulation were able to pick out stuff that they could put to use 
and replace it with something -- at least packing as Bill mentioned.  To me, 
this is what it is all about -- spreading all this good stuff around where 
it is most useful and to prevent its use as landfill.  Feel the good!

The little stereo amp looked interesting so I set it aside.  No tubes --  
probably 6BQ5's?  Make a fun computer speaker amp?  Receiver/Jones-rig power 
supply if nothing else.  The "belled" transformer in the box looked like a 
filament transformer and I would like to find a 2.5v xfmr for a "Jones rig" 
with a 53 or a 7.5v xfmr to play with some 801's I have.  So I set it aside 
too to check out later.  That lightened up the box, but have no fear...  A 
few banana plugs.  A couple precision resistors to use for calibration or as 
matched "A" and "B" resistors in a temporary bridge setup on a protoboard. 
So there WAS some interesting stuff in there after all despite Bill's 
attempt to warn me. <g>

I have a new box.  Spring/Antenna-season is nigh so the box now has 6 pounds 
of 6" ceramic spreaders layered in the bottom -- enough for 150+ feet of 
open-wire line.  I have more if needed -- I didn't want to fill the box with 
only ceramics.  But I did also put in a few 12" spreaders (for a multi-band 
dipole?).  And some fairly heavy duty end-insulators.  A couple of ceramic 
feed-throughs that can probably each be split into two "bee hives".  Some 
air variable caps -- small to medium sized.  A bunch of high-C compression 
trimmers good for low/medium-power pi-net output caps, or series-link 
coupling caps. Two tubes -- an 813 and a 4-125, both unknown condition.  The 
813 is a pull from a ART-13 and I don't remember how I came by the 4-125.  I 
wrapped them in styro-sheeting -- hope that will be enough to protect them. 
The wrapped tubes are in plastic ziplock bags to contain the pieces should 
they fail to make it in one piece.  An R-175 RF plate choke.  It is not the 
"175A" model so it will fry if used without modification on 15 meters. 
Several other small/medium sized ceramic-core pie-wound chokes.  A matching 
pair are "stand-up" -- perfect for a breadboard Jones xmtr.  (I kept a pair 
myself).  More 88mHy telco toroids (although several samples measure only 
82 - 83 millihenries).  Miscellaneous goodies.

And that makes for a bulging box without any extra padding and not much room 
for the contents of the old box.  I will keep some of the old box after I 
spread what I can of the better stuff throughout the small voids of the new 
box.  I don't think the box will make it back to Bill's 31 pounds but it 
will be close.

I didn't think to throw in sockets for the 4-125 or 813 until after the box 
was bulging.  If I get a request for them before Monday, I will pull 
something out to make room for them.  In any event, come Monday noon (Peggy 
closes up shop early) -- look out Ian -- It's comin' at ya!

Hope Peggy has my parts from Thailand -- it's past paypal's 45 day guarantee 
period.

73, Al

*********

My "longshot" want list:

1)  A dual 5 megohm log taper pot (or a dual 5 -15-meg linear pot that I 
could shunt to make it quasi-log) -- for a selectoject.  I am considering 
using a pair of shunted 10 or 15 meg single pots from Alltronics.  I would 
hope that they could be coupled face-to-face, still with some means of 
adjustment.  Bevel gears?  That won't work if they are both log pots, but 
would work ok with shunted linear pots.  Mounted crosswise with a large 
wheel that extends through a slot in the front panel?  Mounted side-by-side 
behind the panel with large gears (from ARC loading coils?) on the shafts --  
then drive one with a shaft extension through the panel?  Or, with a pinion 
gear between the two larger gears?   Regardless, a dual pot would be so much 
easier.

2) A pair of period bypass caps for a Jones PP rig.  I have everything 
except those two condensers and a tuit.  (I would consider even bad caps 
that I could mill out from one side (the bottom) to insert modern caps.

3) A 2.5v filament transformer for the 53 Jones rig (and possibly a future 
super-gainer using 2.5v tubes).  This is a long shot I know -- the audio 
people have these sewed up.  I will probably end up "unstringing" a 5/6v 
transformer or using a 5/6v transformer and dropping resistor -- or beg a 
6A6 from someone (I have several new 53's but no 6A6)

4) A 7.5v filament transformer for an 801A rig.  -- again made unobtanium by 
the audio folks.

5) A 6.0 Henry +4% / -20% (I can't go much over 6H but I can add a little 
series inductance if I have to) Audio Choke.  A power supply choke won't 
do - it has to have a minimum Q of 12 @ 1KHz, more is better.  Does anybody 
have any high-inductance toroid or pot core coils sitting around?  This is 
for a Westinghouse-type SSB phasing network.
