[sdiy] Moog Memorymoog clone almost completed

[Luís Marka]

I used Bourns PTH901-030S-103B1. Ideally the shaft would have to be 
longer, at least 35mm but I could not find those.

It was impossible to find the original potentiometer with the built-in 
reduction gear so I had to improvise... have not done it yet, but I will 
add a few resistors to make a "coarse" and "fine" control in the same 
pot. Ideally the outer shaft will range from 10 to 90, and the inner 
shaft will cover the +-10 range.

Cheers!
