Not sure where to put the information, but I will post it if there is interest.
As I mentioned before , I have an original true subwoofer that is still working fine and will restore that one once I am done with the MK2 that I just bought. All that the MK2 needed was a few capacitors in 13v power supply area replaced. One actually detached from one of its leads , I am assuming from the vibration that it is subjected to. Non of mine were glued down. I statically tested all of the semi conductors , then brought her up with dim bulb and variac , then full line power. It can deliver about 625 watts into a 4 ohm resistive load , if pushed harder it blows the AC line fuse. I have started to document the circuits , (voltages , waveforms , clock signals, etc.) and in doing so I found some things that look a little "off" to me (even though, sound wise- it sounds fine). I will finish documenting , then I will replace all of the remaining electrolytic one at a time noting any changes to the circuit behavior as I go.
If there is any interest it my findings , I will post the document once completed.
Thanks,
Bob
