Not knowing much about the PRS10, I'm just wondering if its worth the ri$k :)
You need to hold that price up against the fact that a new PRS10 is $1600.

Hi all,
Been on the lookout for a PRS10 to build a GPSDO+RB arrangement and I see

Assuming these plots are representative of what you are likely to get from
eBay parts (a pretty big assumption right there), the main advantage of the
PRS-10 seems to be at high tau, where the
My experience has been similar to Vasco's. Of three defective PRS-10s acquired
for about $100 or less each, one had a bad MiniCircuits 400 MHz VCO module and
was an easy fix. Another had a rubidium bulb issue that I traced to the
driving FET. I managed to replace the FET, but the
$219 for a bad RB seems to be silly. Sorry I am not that much of a gambler.

Hi
If indeed these PRS-10’s are out of TS boxes (and that’s a real good guess)
there is one other thing to consider:
Not all PRS-10’s are created equal. Some have fancy disciplining firmware in
them. Some have better temperature specs. Some have better ADEV specs. Some

Hi
There is a lot of *stuff* in an Rb beyond just the lamp. It *could* be as
simple as a VCXO centering adjustment. It also could be an alignment
adjustment. I don’t believe there are any schematics out there on these
devices, so it’s a “trace it out and see” sort of fix. Even with the

Is this just a reheat-the-bulb fix or do you suspect something more ?
