    I just bought this amp and the treble pot has a bad static sound to it. Apparently the seller already tried contact cleaner. Also when the Gain/EQ knob is pulled out, the amp gets about 6db louder, even though the EQ is set flat.

    Does anyone know the model pots I need for 5275 Reverb 75 amp? I'm hoping I just need the treble pot and the Push/Pull type Gain/EQ pot.

    Thanks

    Spray lubricated cleaner inside the pot, rotate the pot several times, and test it again.
    Many people don't use the correct lubricated cleaners. OR they spray the outside of the pot.

    :lol::lol::lol:(some bone heads spray the shaft of the pot...):lol::lol::lol:
    Other idiots spray the cleaner all over the circuit board...:rofl::rofl::rofl:
    Deoxit D100, G100, LPS-1. The cleaner MUST be LUBRICATED cleaner.
    "contact cleaner" is not the right type of cleaner ! :nono::nono::nono: Remember I warned you.

    You may as well clean it the right way and see.
    Chances are if you do it the right way, it will usually work.

    Usually cleaning the pot solves the problem, and replacing the pot is unnecessary.

    Yea WD-40 in the pots did the trick.

    Do that again w/LPS-1, because WD 40 will dry out...
    You need to use non-conductive lubricated cleaner.
