Buchla Module Builds

I do not own any Buchla format modules but I do build and repair them for others.  I did build the Buchla 266 Source Of Uncertainty and the Pulser, Cross Fader, and Timbre generator functions in 5U format modules for my system with modifications for MOTM-signal levels.

The following links are pages for Buchla format modules with my photos, build tips, and calibration procedure since the documentation can be rather sparse.
