I dont, think the audio connections had any thing to do with your power issue. You may have a stuck or out of sequence ratchet relay. Check M7 and M5 as per the schematic I sent. You may have to replace the electrolytic caps throughout the receiver. The collector circuit of every relay driver transistor has one.
