I have an old Technics receiver that has some left channel problems. At low volumes, the left channel either doesn't really work, or it cuts out, and crackles. The right channel is fine.

Causes of a Stereo Receiver Not Making Sound. Silent stereos are usually caused by low power, a wrong source selection, disconnected or faulty speaker wires, broken speakers, or a malfunctioning source component.
This receiver uses two STK0177 power amplifier "blocks", each with 10 in-line connectors. The LH channel is highly distorted, the RH channel is perfect. The distortion is present on FM, AM and AUX (with sig, gen. input) so it's not the FM demodulator - it's definitely in the audio stages.Turn the amp off and reverse the speaker wires at the back of the amplifier by moving the right channel wires to the left outputs, and the left to the right. Turn it back on. If the problem stays on the same speaker, the speaker or wire on the bad side is defective.
