Looking for potentiometers like this

[01redcobra]

This came out of a Ross pedal. I believe it is 50k, the carbon is missing from half the scraper. Anyone know where I can find ones like this? I've tried Mouser, etc. and no one seems to have anything close. Looking for Knobs for Ross pedals too. Thanks

There are two ways to deal with this, replacement or repair. Ross is the original owner of the Kustom amp company, and that type of pot was used in a lot of Kustom amps from the 60-70's. I think Antique Electronics has NOS Kustom parts that may replace what you have.

The second approach would be to replace the resistance wafer on the pot with one from a new pot. The terminal lugs will probably not match, but you can just jumper the connections together.
