I sold some speakers to someone local today in Houston and he told me he had a Kinergetics Research Chiro C-500 amp he would sell me for $5 that he is not using. 3 of the 5 channels work and I am considering getting it fixed to use with an OPPO upd-205. He claims that there were some bad capacitors he replaced and burnt resistors but he was not able to make out the values to replace them. Does anyone have a service manual and is this amplifier worth fixing? Thanks.
