Well, I caught a small break. Bill can't find the paperwork he got back from Ten-Tec, but he posted a query to the Ten Tec reflector last March. The 2N4105 & 2N4106 transistors in the audio power amp need replaced. Alltronics for one has them. So I'm going to check and see how many I need and order them (plus a few extra, just in case) right after payday.

One step at a time. I just hope the finals aren't shot, it appears that the originals (2N2631) and their replacements (2N3553) are now made out of Unobtanium.
