For unexplained reasons, I've accumulated a couple of 2m CD Gonset
III's. I restored one to operation and matched the yellow paint. The
second one, also a III, does not match any of several Comm III
schematics I have. Specifically, it is the second unit's power supply.
It does not have the -25v bias supply components installed or wired.
Also, in one book, these components are clearly NOT there, either.
Problem is, all the pull-out schematics I have do not include this
variant. Anyone out there have a Gonset power supply chassis schematic
where the bias supply is not wired up? Thanks much.
