O.K. I think I got it...

I'm going to use the MJE15030/31 part for the drivers. Will replace em all.

I'm chasing a Heathkit transistor tester, when I get it I'll check the output transistors, right now they seem to be ok but I wonder how in spec they are after 20 years or so.

The .82 , 2 watt resistors associated with output transistors, are these metal film, or ceramic or does it matter? I intend to check these with a sensitive vom at work but want to get a few in with my digikey order. Can you think of any other likely suspects in the electronic lineup?

I'm pretty excited about the prospects for fixing this amp, ordered a service manual and now have lustful dreams of stacks of overhauled 555's driving whatever speakers I want to throw at em. Once again guys thanks for your help.

Chuck,

Being DIY guys and all... once the 15030/31 works... the next upgrade would be to try the mje15034/35... so why not begin with those? ;-)
