After having salvaged an old 5065A that was decomissioned in 1987 due to Rubidium cavity heater short circuit, I have now, several weeks later eventually managed to what I think repair it. Using a GPS-Diciplined HP105A as oscilloscope trigger, the 5MHz O/P is absolutely still. "Continous Operation"is ON, and the values indicated on thepanel meter are almost matching thosewritten on the operating chart back in 1987.
The next step is to take the 5065 to my work where we have two H-masers. Then it will be possible to see if it meets the old specification. A BIG Thank You to Corby Dawson!for valuable help and also to people providing the documents found on KO4BB site ("First Aid...")
