    Good evening from the south east coast of Pennsylvania...I found my first Marshall in the snow behind the music and arts store across the intersection from me...an ham-fistedly assembled MG series with reverb. I resoldered a bunch of stuff and it still sings! But I have a brother-in-law amp issue; his little 5501 bass amp needs volume and gain pots replaced for looseness and scratchiness and dead spots. I can't read the hand-written copied-off schematics I see online: what are the pot values? Backs of the pots reveal nothing; haven't got close to the circuit board yet to see if it's stamped there, as I'll have to desolder the speaker leads. Just wondering...Thanks!!!

    You can put a ohm meter on the end and center lug and take a ohm reading for the size of the pot . Greetings from cal

    It is probably the same as the 5205.
    The potentiometers should have markings giving the values.

    Not mentioned, but spray the pots really good firstly, my 5010 now works flawlessly.
