Dual Negative Slopes + Hills & Valleys

Assembled Modules are built to order, please be patient when ordering. Use the contact page if you have any questions or requirements!

An error was found on the current pcb in the Hill/Valley’s section of the circuit. R57 connects to the nodes between pin 2 of Q4 and Ground. The Ground side of R57 should actually connect to V-. See Photo

** 4U Modular is a term used for the format most commonly known as “Serge Format” or “Loudest Warning Format”. Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and mounting hole style. 4U Modular will patch up just fine with other 4U "Serge" formats such as "Random Source", but it will not mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website soon to make this a lot more easy to understand.
