Also note that the *inputs* to the amp can cause a similar problem, I
repaired
an amp that was doing this intermittently. It turned out the
phono-RCA-jacks
*in* to the amplifier had no ground connection. This was due to them being
dual phono sockets, stacked vertically, with no physical support other
than
the solder joints (not good), coupled with super tight fit, gold plated,
heavy cable interconnects -- the insertion force required to get the
line-in
to go in was such that it broke the amp input.

likely bet is a bad joint or cracked print right behind the connector
block.

Either at the input, or output

Hi Mike

This is absolutely true, as a general rule. I too have seen this many times
on even high end Yammies and Teacs. I assumed it not to be the reason in
this case, because the unit has a built in CD, which I took to be the OP's
source when playing his test Beatles track. [ " I put on a Beatles track
to better test it " ] It sort of reads like the available input sockets
on the back secondarily produce the same result, [ " I tried the two
available inputs, ( "DAT" and "AUX" ) - same thing " ] so this would
indicate an output rather than input issue. It is a shame that he did not
post just one more picture looking down on the print side of the output
connector PCB, which he has otherwise completely exposed. It may have been
possible to see whether or not the joints were bad there.

I wonder if the OP has got anywhere with it yet, as a result of all the
advice offered so far ?
