Buchla Module Builds

I do not own many 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.  I also have my own 208 Music Easel.  There is good historic Buchla reference material at www.fluxmonkey.com/historicBuchla/BuchlaIndex.htm

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