• SX-64 Whine

    From Frank Linhares@39:905/0 to All on Mon Dec 9 21:15:14 2019
    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?

    Nope. (With any electronic device, but my ears are as old as yours ;))

    Could it be a bad ground?

    The first thing I would do is (visually) check the capacitors. Bad ones are easy to spot. And are the first things to go in old devices (maybe new ones too :-()...


    Bye, Wilfred.
