[sdiy] potentiometers wanted suitable for moog prodigy knobs

[Florian Anwander]

Hello,

I am looking for a source for potentiometers with a "half" 6mm shaft - 
like the are used for knobs in EH effect devices or in the moog prodigy.
I am looking for 50k or 100k lin and log.

The local electronic stores and the music related spare part 
distributors here in germany don't sell them.

Any hints for a distributor?

Florian
