P A R T S

The following are parts that I have extra of as a result of repairs or projects. In most cases I was required to buy a larger quantity than I needed (sometimes by quite a lot) in order to find an identical replacement part. The parts can be ordered by PayPal. Email me.

Proud member of Analogue Heaven and Synth-DIY.    My eBay items for sale page.

View the images alone to see a larger version. Many of the items can be reordered/backordered.
I did not take all the photos, but they are always representative of the part.

4 position slide switch C&K, C & K - L Series Miniature Slide Switches.
Part Number L204-09-1-MS-02-Q same as L204091MS02Q
This is a DP4T CK slide switch, PC mount with a 0.25" actuator height.

Very similar to L204011MS02Q and L204121MS02Q. See this page for comparison.

It's possible these might work for a Pro One or Octave Cat, but you have an extra position or two that you'd just cut the legs off of I imagine. I've never tried that, but I have so many of theses, it's a waste to see them sit around.
