This is the expansion
(unpopulated) accessory board that works with the CS80 FIlter MkII to provide a single wiring harness for eight accessory jacks as used in the CS80 filter MkII. It is designed to hold Switchcraft 112APCX type jacks and facilitates the use of two (user-provided) 10-pin (2x5) flat cables to connect from the jack board to the filter board. Note: this is the board to expand the filter for all filter taps as well as the jacks for the linear VCA. This board can be purchased as part of a set, see the CS80 Filter MkII Rev2.2 Bare Board product entry in the catalog.
