Unit came in with intermittent tuner audio. 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?
Thank you.
