Hi all,

a friend of mine has a PC piano where the PC suddenly started to play wrong notes, the whole song can barely recognized. The red light at the tape deck is off showing that the tape synch is OK. Replacing the tape recorder with a second one and the tape replacement circuit shows the same effect so my guess is that the error comes from the playback board. Could the error be a wrong adjustment of any of the potentiometers (the sudden error speaks against it)? Andy other guess where to look? The capacitors seems to be OK, they have no short.

Thanks for every hint!

Best regards,

Michael
