    Hello...

    I have a Marshall 425A cab with the switchable stereo/mono jack plate...

    Can anyone tell me which posts on the jack plate are (+)?

    (Maybe call the posts "1", "2" ,"3" and "4", from the left to the right in the pic?)

    I am not sure how to tell and I have the feeling it was wired wrong because it sounded kinda funky...The one picture I found on the internet was different from how mine was wired

    Thanks,

    Dan

    Hard to tell from the pic/flash, but just follow the traces.
    The jack contacts nearest the plate are the shaft -
    The jack contacts furthest from the plate are the tip +
    Follow those to the four posts. From left to right it looks like - + - +
    But verify for yourself.
    Do you have a meter.?

    Thank you ZZ...

    So with the solder points on the furthest left being #1 and the ones on the furthest right being #4, negative is posts #1 and #3?

    That is how I see it. If you do not have a meter, just insert a cable.
    You will see where the tip (+) connects
    and where the shaft (-) connects.
