292M (no
letter) Quad
Lopass Gate |
|
The 292M (no letter) Quad Lopass Gate is the original version which does not use vactrols but instead diodes.
The original had a hand wired panel but this version uses a panel PCB designed for this module and the 292A. Neither had an All-Output but the summing op-amp was included on this panel PCB if the user so desired.
The white wire is -15V to the all-out op-amp.
The main PCB shows the typical symmetry and you can see the 6 diodes in each filter section.
The module is still under construction.
