  • Vox AC4TV power attenuator switch problem

    What I have in my hands is 2010s little AC4TV amp with "power attenuator" roatry potentiometer with 3 positions (1/4W, 1W and 4W full power). Switch went bad inside, probably someone tried to turn it with force that's my guess... Anyway, it's soldered on a little board. Tried to show where the pins of the pot are soldered via violet circles.

    Managed to trace the exact part, but it's unavailable in Europe, but I could try to fit something similar (pic below). But /i found only "3-poistions and 4-circuit" version (or version with more than 4 circuits). Quite dont get how I solder it to that board, can someone point me how to do it right?​

    Why not fit a Lorlin/Alps 2 pole 3 position rotary switch. The 6 position will configure to 3 position by moving the collar around.
    Plenty of variations available from Mouser, RS, CPC, Farnell etc.

    If you can't fix it, I probably can.

      UK is taxes, custom and expensive shipping. Will try Mouser database too. Well Im looking for cheapest way, because this pot you linked, with shipping and taxes will be like less than 1/10 of price of the AC4TV....
