My Serge VCFQ was bought as a semi-kit from SMMS (Serge Modular Music Systems) in the early 1980's

Serge modules are available from these sources:

Random*Source: Serge Tcherepnin is the “Chief Innovation Officer” for Random*Source and they are currently producing classic modules and new designs. Currently there’s no DIY option to build thier designs.

Prism Circuits: Serge Paperface modules are available to DIY. The focus is on early 6 row designs and the paperface build style.

Loudest Warning: Custom builds in Loudest Warning format and full panels. Panels are also available for DIY.
