    I bought a used Ampeg SVP-BSP from Ebay. I know, its power supply can be wired to work from 110 or 220 V. Has anybody made that or maybe somebody even have a diagram? Thanks.

    For 120V, the black wire in the mains circuit is on J26, and the brown wire on J27.

    For 220V, the brown is on J26, and the black on J27.

    In either case, a white wire should be on J29

    J27 is just a "storage" position (so is J28), J26 /J29 are where the mains power is.

    Thanks a lot!
    Now it works!
    It was so simple.
    p.s. Sorry for the mistake in the thread. I meant: "120 to 220 V".
