[time-nuts] Nifty old GR OCXO? (looking for information on693-A SYNCRO-CLOCK)

[jmfranke]

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.
