True Sub Volume Knob/Pot bad

Post by airboyd » Tue Oct 25, 2011 1:14 pm

Thanks to this forum and some quick searches, I determined my volume pot is bad. Tightening the nut made it worse.

It started with a hum starting after playing bass or explosions etc. Tapping on the amp panel on the cube made it go away.

I opened it up and it's looks slightly different than the other two and has extra wires soldered on the side. I was thinking about just swapping it with the other two, but it's clearly a different set-up.

Is this a simple fix for a not-so-good-solderer or should I send it in? Obviously, trying to save money if I can but not destroy it.

Any other repair advice appreciated.

Try some deoxit/fader lube first.

Hum's more or less gone. Has anyone ever tried the RCA inputs to XLR on an older sub?

Wow....only took you a year to respond! LoL So did the DeOxit solve the issue?

Adapters from/to XLR CAN sometimes introduce noise, but you don't know until you try~
