Any amp repair techs in the house? Need data...

Trying to resurrect some old fogie amps. Oldies but goodies.

1. an ancient Alphasonik A240B. (1984!)

2. a not-quite-as-old Alphasonik PMA2100

3. a Proton 222... though I think I MAY have that one figured out. (BTW: This ain't the one I got from you, Prowler573! That one's working fine! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif )

4. a first-generation Rockford Punch 150 (~1985). Though, I seem to be missing the bottom pan (sheet metal cover) for that one...

5. a Rockford Punch 75 MOSFET (first series of MOSFET RF amps, about 1988 or so)

6. a Zapco 151A (the three-piece amp)

7. an Alpine 3517 (30w/ch, from about 1985)

Anyone got any schematics on ANY of these amps? I've been figuring it out by myself, without them, but it certainly takes a LONG time!

Thanks!

Regards,

Gordon.
