Problem below fixed by replacing the outputs, bottom board..2 2sd313 and 1 2sb507 Now, both phono outputs are intermittent and not consistent. Tapping, flexing boards, wires and I can not generalize the problem. I remove the two switches, cleaned them and no help. When it goes off, the relay clicks and anywhere from a second to a few seconds clicks back on. Tuner plays consistently..thanks to ABL Elect and others for their responses on that problem. Thank you.

Other inputs are fine. I traced the problem to a PCB on the bottom of unit, right beside the AGC fuse board. PCB has an intermittent connection somewhere, flexing the board and I can make the problem come and go. I've been all over this PCB with a magnifier, soldering iron, cleaning it with print-kote solvent. I've pulled the large capacitors, cleaned the glue from under them, remove the three transistors on the heat sink, cleaned the terminals and replaced them. I checked the traces near the screws for the heat sink, especially. I did find one solder pad with a bad connection and replaced that. I checked voltages while unit acted up and didn't find any missing. Moving each wire one each terminal does not affect the problem, so I am convinced the problem is on this board. I shine a bright light and checked with magnifier and am stumped. Has anyone ran into this problem?
