I have a fisher ca-272 home amplifier that is giving me some trouble. I bought it off of a guy that knew nothing about audio equipment, and had hooked a jumper wire across both left channels (I am guessing to try to bridge the channels...) and he said it played a little bit and when he turned it up it went silent. I am looking for a schematic to look from, it doesn't look extremely complex... I did notice that it blew one of the fuses... It uses two 4a 250 V fuses. I am not sure if jumping the channels like that would have affected the amplifier portion of the circuitry of not... Can anybody help me on this one????
