  • 72 JCM800 standby switch - where to buy?

    I'm fixing a 1972 JCM800 Super Lead 100W. The standby switch seems to be flaky - it takes a few tries to get voltage, and sometimes it does this while playing.

    The hard part is finding one with the black plastic knob to match the other two.

    Thanks!

    BTW
    The other issue is the impedance selector, which is pretty loose.
    The owner is thinking of replacing it with a modern one.
    I went ahead and soldered a wire to make it 8 ohms.

    This may work. It's a rocker right?

    Mouser also has pages of rocker switches.

      It's a regular switch with plastic knob; not a rocker.

      This is similar, except the handle (bat) is black plastic instead of chrome.

      BTW - output tubes bias is 540 volts at 17mA --- YOWZA!
