The Serge Gain Cell is a sub-module used in various Serge designs. The CGS508 supersedes the CGS108(*).
3D Model
The circuit is proprietary and consequently is now only available as a pre-assembled sub-assembly and supplied for use with the relevant modules eg CGS512 or ES33.
(*) The CGS508 has the same pinout as the CGS108 and so can be used as a full electronic replacement. However, as the CGS508 is part of a complete redesign/replacement for the CGS101, the CGS508 is supplied as an assembled module with header pins that require the module to be mounted parallel to the main PCB. This makes the module unsuitable for retrofitting to CGS101 PCBs.
