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.

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