picked up a silver faced fisher receiver today model no 143? says sears audio by fisher, all lights controls etc work but the left channel is weak, opened it up and looked at all the circuit boards found one resistor that looks suspect(kindve burnt and black in the middle) has the fisher hybrid ic pa 501 power modules, i cleaned all the switches and pots(no static) so if replacing the burnt resistor does not fix the left channel any ideas? i measured the dc offset and got 9.5 to 10.9 in the left channel and 44.5 to 48.5 in the right... ill try to post a picture later thanks for your help!
