I recently picked up a Commodore SX-64 and am completely in love with it.

The unit is in amazing condition and the previous owned cared for it with
lots of TLC.

I do have one issue that I am hoping other may have run into. When I turn the
unit on, it emits a high pitched whine. My nearly 50 year old ears can barely
register the whine, but it drives my kids crazy.

I am wondering if anyone has experienced this before. Could it be a bad
ground?
