29th Juillet 2019 – Added corrected wiring diagram, amended CGS link, added Mouser BOM.

This following page details a possible means of construction for the CGS/Serge Wave Multipliers utilising the single function 4U panel from Loudest Warning.

The PCB’s (CGS 113) are available from Modular Addict here and more detailed construction notes (and information about the module) are here

Loudest Warning CGS/Serge Wave Multiplier panels are available from Modular Addict in the US.

This panel utilises Clee’s 4U Bracket, also available from Synthcube and Thonk and Modular Addict

Mouser Bom:

Copy and paste into Mouser BOM uploader, note that this is only the PCB components, includes all 47pf caps, 30pf caps, BC557 subbed for 2N4250. Double check, remember it’s sometimes cheaper to order 10 resistors than 3. Includes banana sockets and IC sockets but not knobs, pots, switch, power connectors or wire etc, no beads, no hardware. No 3080’s (13700’s work well in this circuit) etc etc
