Excellent repair coverage! Thanks a lot Timo. It looks like apart from wooden sticks

virus is very well designed compared to some other devices I have had a chance to see disassembled.

Has anyone been able to match up the Pots to anything in the Mouser/Digikey catalogs?

I just bought an Indigo with this problem. The previous owner had been going to fix it, but decided to sell it instead. He had already communicates with Access and they had invoices him- and the part number is on the invoice. The part number on that invoice is RK11K1140A23 which appears to be a standard part available through Mouser.

This thread should be stickied.

About the pots...

Here was my original thread, when I was trying to find the pots used (before contacting Access' hardware branch to obtain them).

http://infekted.org/virus/showthread.php?t=24791

http://SynthesizerService.de stated the pots are 10K Ohm linear.

These are easy to find, but ones with the same spindle dimensions as the Virus uses are not. The Virus pots have spindles that are exceptionally short.

Above shows the measurements of a general potentiometer spindle.

However, for the Virus, the 'Z' measurement is 0mm (it sits flush with the top of the nut), and the 'Y' measurement is much smaller than usual. So an off-the-shelf 6-legged, 10KOhm vertical pot like this, for example...

... (the one on the right), or the one you pointed to in Mouser (well, at least the graphic of it), wouldn't be any good, as the knob would be sticking out by a mile. At the same time you don't want the 'Y' measurement to be too small, or the bottom of the rubber knob will chafe the surface.
