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.
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.

Rockford will supply schematics for their older (out-of-production) amps except for the BD amps.
