Buchla Module Builds

I own only a few Buchla format modules so I do builds and repairs for others.  I did build the Buchla 266 Source Of Uncertainty, Lopass Gate, 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 and built a pair of cabinets for my other Buchla modules.  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, operation, and calibration procedures.
