I agree, I was mainly just trying to make the point that the tube tester I sent you isn't as obsolete as you thought it was, that's all. Like I said I'll still check my tube stash out at home for the tube you need or its substitutes and get back with you about it. I had a birthday party to go to earlier and I also had to repair one of my tires because it had 3 nails in it and was low and I was checking into getting some new tires for my car as well so I won't be getting home as soon as I thought I would today. Don't worry I haven't forgotten about you!
EDIT: I just looked through my tube stash and had two boxes labeled 3AW3 (which is a proper substitute forthe tube you need) but that's all it was, just the boxes, the tubes inside them weren't even close to being 3AW3 tubes, one was a 1B3GT tube (which I'm not sure why a tv repairman would put a 1 Volt tube in a box for a 3 volt tube and is definitely NOT a suitable substitute for the 3AW3 let alone a 3CU3, and its not even the same filament voltage) and the other tube was a 3DB3, which I guess is a substitute for a 3AW3 and also a 3CU3, If you want the 3DB3 tube I have (I'll test it first to see if its any good)I can mail it off to you, for the price of shipping.
Well I tested the 3DB3 tube I have and it almost pegged out my tube tester on the good side of the meter on both the grid leakage and emissions tests. I'm kind of starting to see a pattern here, its almost like whoever owned this tube caddy before me was apparently a dishonest repairman and replaced tubes inside TVs and radios that didn't need replacing just so he could upcharge his customers for repairs that weren't needed, kind of like how auto mechanics work sometimes...
