  • Marshall code 50 power supply components

    Hi all
    I have a marshall code 50 Combo
    with a blown psu. I have spoken to marshall and they said that they don't have the smpsu diagram for this model
    I asked about a replacement board, But this one is no longer being made

    So i either give back or try and repair. I have one resistor blown and have no idea of the value
    R10. does anyone here have a scrap board or have knowledge of the same fault
    Once i know the resistor value i can order along with other compenents

    Marshall did send me a schematic , but i think its for the current model and has no smpsu

    many thanks in advance
    Mr A

    Looks like a relatively simple SMPS.
    Check the switching mosfet for a short.
