    Late last week I received a ST-70 to fix. Had a intermittent hum and a mistake on the SDS capacitor board. Attached are 2 photos, before and after. It was a little mess, but its presentable now.

    I also replaced the 2 bias potentiometers as the wrong value was installed, new speaker terminals and RCA jacks.

    Sorry for the flash glare.

    Enjoy,
    Sal

    Thanks,
    Sounds better too as the electrons flow a lot quicker without all the bends in the wires... :-)
