[R-390] Lucked out bigtime yesterday

I'll bet those IERC tube shields are old and have lost most (if not all) of their shielding/heat-wicking ability.  Those tubes probably are burned out, and those miniature tubes -- well, they're probably useless as well.  And that transformer -- it's probably shorted out.

Besides, you'll probably have to actually pull out the tube shields and tubes yourself, not to mention you'll have to disassemble some of the unit just to get to that transformer.

Yep, I'd just close 'em up now and put 'em aside.  They're just about useless.  Better still, just pack them up and send them to me.  I MIGHT could find some use for some of those spare parts.  Of course, you'll have to pay shipping...

Subject: [R-390] Lucked out bigtime yesterday

Did I ever luck out yesterday!!! A couple of weekends ago, I brought
home from a local QRP-club meeting two MIL units having something to do
with tube synthesis. Both units were about 5 inches high, and weighed a
ton. Each. I took them because I make it a firm policy to never tyrn
anything down. You just never know... right?

Finally got around to snaping open the top and bottom panels on them
yesterday. Neither one was ever goung to work again... both having
cables and wires cut inside, and one with apparent partially complete
homebrew mods. No serious timebase in either one (which was the main
thing I had thought I'd find. In fact, no crystals at all.)

But... there were 26 IERC tube shields in one of them!!! Just what my
R-390-A needs! Or my 51S-1... probably the latter now that I think about
it. Lots of other good stuff... one medium voltage hermetic transformer
each; about 25 tubes; 6 or 8 of those miniature (little-finger-sized)
tubes with parallel wire leads; etc.

The efforts were worth it just for the tube shields!!!
