Can be caused by any one of the three typical problems with all the 70's amps & recievers. Either the Diff. Amp. Transistors are bad in one channel, or the power supply that feeds negative 30 volts to the Diff. Amps. in both channels is not close enough to 30 volts, or the protection circut is not turning on the relay to the speakers. The way to tell is:: With the power on & volume down, measure with a volt meter (switched on to DC), on any end of the four large white resistors on each power amp.PC board. Any, or all four should have about zero volts on each. if any have more than 1 volt DC., measure the other four large white resistors in the other channel. If they also have more than zero DC the problem is in the power supply. If only one channel has more than zero DC the problem is in that power amp., not in the power supply. If both channels are at zero volts, or both are at one volt or less, the protection circut is the problem, it is not turning on the relay to the speakers.
