You are watching sliding potentiometers for the Elka EK 22 and EK 44 as well as the related units (EM  22, EM 44, ER 33 and ER 44). They all use 3 identical pots, except ER 33 that only uses one. Elka OMB5 uses 7 of these. This is your chance to refurbish your precious synth with brand new pots. No more data values skipping or noises. It's very straight forward to replace assuming you can use a soldering iron and a solder pump. I can help with instructions if needed.

These are NEW pots, not new old stock. I have sliding pots for most vintage gear, including most Korg, Yamaha and Kurzweil. Some rotary for older Moog (Micromoog) and Transcendent 2000. Also some switches and some SSM and Curtis (CEM) chips. I will be selling all these in the next few weeks. Contact if you are looking for something. I repair (and collect) synthesizers since 1992.

I will send worldwide (tracked mail) and the price will be the same no matter the quantities.
