Just purchased a Nakamichi PA5 and it runs good and warm but it has a constant low level (60 hertz?) hum, equal and non-changing in both channels. Otherwise, audio signal sounds good. Any suggestion on how to get rid of hum? Based on other threads, I am considering replacing electrolytic capacitors, will that solve my issue? Thanks, Robert

test with inputs wide open , same as with inputs shorted
if it still hums , in both cases , caps are most probably culprit
though , pic or two can't hurt
