[time-nuts] Maser manual (2)

[Kit Scally]

John,

I'd put money on one of the feedthrough caps (easily damaged upon installation) in the Maser for such small jumps.  
>From memory, the 5065A uses SM components, but these could be guilty.
 
I've learned many abstract things I'd never otherwise come across in this thread on home-built masers.  I for one would like to see more mileage on this topic although I'm not sure there's $25k in my "Xmas box" for the necessary parts to build one !

The 5065A is showing occasional phase jumps on the order of 10-100 ps that
coincide with small spikes in the current drawn by the lamp exciter, and I'm
leaning towards blaming the silver-mica B-E feedback capacitor.  (It even
has the same designation in both instruments' service manuals, C2.)
Tom: this is why your BVA was appearing to jump when I measured it. :-P
