These are the build notes for the NLC version of one of the classic filters of all time: the Buchla 292.
The 292 configuration consisted of 4 filters with CV control & a 3 pole toggle switch for each filter.
The toggle switch allowed you to alternate between 3 modes: LowPass, Combination & Gate.
Gate is Buchla's name for a VCA.
Buchla still produce this filter in two forms: The 292h& the 292e (which goes by the grand title of "Quad Dynamics Manager").
Here are some pics of the virgin NonLinearCircuit PCB & panel:

The 292e is the centre module. Notice that the toggle switches have been replaced with buttons.
It has also gained velocity control & preset storage but is mostly the same as the earlier 292.
