[time-nuts] Mystery hp Ovens For Sale

[Tom Van Baak]

Hi Peter,

Thanks for your keen eye and for sharing this with the group.

That massive foot-long cylinder is from the late 60's double oven HP 106, the best vintage quartz frequency standard hp ever made. I have some here in the "museum"; short-term stability near 2e-13, long-term drift around 1e-11 over 40 days (3e-13/day). Very rare these days. Based on a massive ultra high stability 2.5 Mc quartz resonator. Truly a thing of cold-war beauty inside. See also:

Of course, there are no guarantees that what you saw was in working condition. And it's missing the rest of electronics. But if someone wants a "project" it is worth it, even at ten times that price. Surely someone on the list can give it the attention it may need. Whoever gets it, please contact me eventually for suggestions on bringing it back to life. It deserves it.
