Model 165 Dual Random Voltage Source

Produces two uncorrelated, random output voltages, each of which is changed by applying a trigger pulse. Used to randomize frequency, amplitude, and time.

The circuit used is a functional replacement for the 165, based on the random generator circuit from the later 208 Easel (simpler and more reliable).  For the Dual Random build using this panel, you will need 2 PCBs.

Pcbs and panels are in the shop here, and here (respectivly).

Alternativly, if you are in the United States, you may like to order pcbs direct from fluxmonkey.
