Joe:

I have downloaded your instructions for defeating the tone controls in my PAS. I would like to perform that operation in a couple of SCA-35 integrated amps, too. I'd like to keep one and give the other to a friend's kid going off to college. I've read descriptions of the SCA-35 preamp circuitry ranging from "a PAS grafted onto a SC35" to "a completely different cicuit), though the latter seem to primarily refer to the dual vs. seperate pots. I dunno. I've read Roger Stevens instructions, which 1)much more complicated, and 2)resultant of weird side effects.

Can I use your method with the SCA-35s? (I realize that it wont transfer literally, i.e., I'll need to identify anaolgous leads and board terminals) Maybe something similar?

Any guidance you can lend will be greatly appreciated. I do have schematics to all the Dynaco amps.

Very truely yours,
Dave Osborne

PS: Thank you for unusually clear written instructions.
