[time-nuts] Rubidium Oscillators

[Brian Kirby]

A used good bulb usually runs right at $50 on flea bay....

I talked to Efratom years ago when they were running the show in the 
middle 80s.  A new bulb was $400...

And they aren't absurdly expensive on Ebay these days - bet a new bulb (if even available) is almost as much as a  used but working rb off Ebay.
