Nifty old GR OCXO?
I did find some information on the 693-A in a partial installation manual
for a C-21-H Standard Frequency Assembly. I can scan the one page that at
least shows the rack wiring harness if that would be of help. Or I could
loan you the partial manual so you could tell more about the high volyage,
etc.
How come your address does not work?

SYNCRO-CLOCK)
While we're on the old GR subject...
I have a General Radio 693-A "syncro-clock and amplifiers" that contains
a GR model 611 syncro-clock module. I think the oscillator and power
supply
are separate (and I don't have them). Does anyone have any information on
the 693-A?
(Copies of a manual would be great!)
I'd like to get it running within a decade, and given the number of
projects I have going at once, I should start soon.
Don't know if this helps, but there is a decal on that back that says:

Your address bounces.

I have the manual for the 1123-A,-AD and a working 1123-A. I can loan the
manual, it is too large to scan.

I have a 693-B which has a large dial, the internal 1kHz amplifier,
and the
power supply. I also have a 1103-A which requires an external power
supply.
They are slowly moving up my to do list. The only manuals I have
are for
the 1103-A. I would be interested in a manual for the 693-B.

And I'm still looking for a manual for the GR 1123 synchronometer.
