    Sovtek MIG 100U Schematic Input Jacks

    Greetings!

    I have a Sovtek MIG100U in my shop for repairs.
    Someone had previously attempted to rework the input circuit.

    The MIG100H input jacks do not match.
    Looking for MIG100U schematic (or correct input jack wiring diagram).

    I've attached some photos. I'd like to put it back together.

    Thanks.
    Tom

    There are some slight differences- notably different resistor values. I can't read the values of the resistors in your pictures. Look at those and see which schematic they match up to. Then wire it like that schematic.
