  • Help Finding Replacement Amp Parts

    Hey All,

    I have a 91 Red Knob Fender "The Twin" that needs some pots replaced. Six to be exact but I am down to needing to find just one but its needed at 3 different locations on the amp. At Channel 1's Treble/Pull for Cut, Channel 2's Bass/Pull for Boost, & Main Volume/Channel Select. I am providing links to the exact part so maybe someone could direct me to a generic, another place that sells these OGs (in stock) or a different idea totally.

    Fender Control A250K 20% Audio push-pull 0025946000

    can this work

    http://www.allparts.com/Bourns-250K-...p-8285-000.htm


    PS-Of course by this point I have talked to fender and they say nope we dont make em' anymore. I talked to darren at http://www.darrenriley.com/ he said he has seen em, touched em, taken pictures of em, even put a few in, but he aint gettin anymore in. Talked to a couple electronic supply but my knowledge there is slim so I was directed back to fender. Anyone... please help.

    Your chances of finding exact replacement pots are pretty slim. The only way would be to find someone parting out an amp with all of the parts that you need.

    You can use the All Parts version, but it will probably not fit directly into the original pc holes, and the knob may or not work with the knurled shaft. You may need to connect the pot and switch to the board with small wires.

    Generally I try and find the closest electronic specification match and then try and work around the physical differences, like the wiring and knobs. As for pot tapers, get whatever is closest to the original values, and be happy that the amp is usable. The controls may not work the same as before, but they will work.

        If Fender says they no got them, then they don't. At this point you will have to find some parts dealer who stil has some in stock.

        For example Parts Is Parts has some of the other values

        26048 | www.guitar-parts.com

        And the 25k and the 10k,

        But I don;t see the 250kA.

        Your Allparts might work, hold your dead one up next to the photo. Shaft is different but live with that.

        Mouser has this, it is only 100k and linear, but I bet we could adapt

        RV16BF-20-15R1-B15 Alpha (Taiwan) Potentiometers

        I still have ONE of those in my drawer, but I am holding onto that for repairs.

        Might be able to adapt this one

        Fender Stratocaster (Strat) 250K Push/Pull Pot

        ANd just call various repair shops, all you need is for three of them to each sell you one.

          If it will fit, put in Alpha or CTS pots and run leads to the PCB. You'll never have to replace them again.

            Thanks guys, I ordered the ones I could get still but the 250K is a mutha. I ordered the one of the 250K (though I need 3) just to see if I can make it work. I am sure I can but money is tight so I want to be sure.

            Seriously I appreciate everyone's help.
