this AIWA LCX-AC1 stereo works in all modes but cassette. when play is
pressed you get a thunderous crackle and hiss. This unit does not have
thre traditional rec-pb slider switch, which is usually the cause of
these faults; it seems to be done electronically.

the noise persists even with the heads disconnected from the main pcb.
I have tried heating and cooling the area to no avail. there is one IC
I suspect, labelled 4560 0695 , 8 pin and is smd. can't find
references to it.
Anybody have a schematic? or any other suggestions.
cheers,
