Please help me with a SB200 Sunn Bass Amp
« on: September 07, 2009, 01:36:28 pm »
Hello, I need to rebuild the power section and nobody can find any information on this amp let alone a schematic. I was really hoping someone could post a picture of the power section with the polarity of the filter caps and where the .02uf 1400 vdc ceramic cap located by the PT fits into the circuit. Or even a simple hand drawn diagram. Also need to know if the two circuit boards should have a common ground. Somebody pulled this from a combo and built a custom head case and i don't believe they ever got it working right.
   I have been going nuts trying to get this thing back to good and would really appreciate any help.

Thanks,
Mike.
