Hi Marshalls

I have a oldish AS50R that sits unused most of the time. Wanting to use again but hampered by vol cutting out as the vol knob is turned. Tried openingup cab and spraying WD40 contact cleaner stuff. I think I might need to replace the volume control unit and would appreciate advice. Local amp shop would step in but they are way behind and expensive. If I need parts where can I order from?

Basically - can I fix this myself?
