Hi Everyone,
Can anybody tell me if the volume pots and tone controls Peavey used in their amps conductive plastic or carbon? (Example: LTD 400, NV 400, Musician, Deuce, etc.)
I'm guessing they were conductive plastic but not sure.
Can anybody give me the answer?
Thanks,
Don |

| Don, not sure but I have a couple that I changed and can open up and look. My guess would be plastic. I will report back later today. |

Thanks Larry! How I clean and lube the pots will be determined by your answer.

Don. They have no carbon brush. Appears to be a plastic wafer with a brass wiper. This was from a Nashville 1000 gain pot.

That's actually a carbon pot. They use a metal wiper on the carbon arc that is on the phenolic base.

| Michael, thanks for the extra information. I couldn't find the actual spec on it to reply properly. I have cleaned these with good results using Radio Shack tuner cleaner with lube. Still available on their website. |

I just cleaned my Nashville 400 pots with 99% Anhydrous alcohol after reading a post on the subject. Guess I will have to go back in and put some sewing machine oil in the pots for lube (note: a small amount only).
That said, does anyone use TriFlow to lube pots?
Did Peavey always use carbon pots or was this only for specific applications?
Thanks...Don |

They always used carbon pots. The cost of the plastic film would be too prohibitive. The price difference between an Alpha/CTS carbon pot and a plastic film, like Bourns, is high.
