Virus surgery: Re-Potting 101 (warning - many photos!)

[Timo]

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://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.
