-Based on the Buchla 265 Source Of Uncertainty but without the rare components+Based on the Buchla 265 Source Of Uncertainty but without the rare components. This module happened when I was asked to get a friend'​s rather expensive SOU265 clone working. The PCB was so full of errors so it seemed easier to simply design a new one. I don't like designing for rare components and ridiculous power voltages so started from scratch. If you break the SOU265 into sections, it is a white noise source with filtering to get slower random voltages. These are fed into a 100Hz triangle oscillator to wobble it. One output is fed to a sample & hold, with feedback, for the stepped output. The other is fed via another S&H into a LPG designed for CV rates and controlled by a very crude VCO (its not like it needs 1V/oct) to get the smooth output. 
 +Please note - the current panels are 10HP white/​gold
