Bob,
The vendor has said that they did not want the unit back. So...
I opened it up. Crudely, I admit. I learned a few things. I was concerned
about the outer case heating up too much when I was trying to remove the
solder. Turns out that the outer case doesn't touch anything except the pins,

Hi
The one advantage you have in testing a used OCXO is you have a pretty good
idea of how
you are going to use it. If phase noise does not matter to you … no need to
test. I’d always check
that it tunes on freq with reasonable EFC range left over. I’d also make sure
that it warms up

This tube type item on ebay is equipped with E1T high speed decade counting
tubes.

projects ..Lets say your personal time is worth $50/hour (cheap cheap
for a professional today) let's say you have to spend 10 hours testing
this oscillator that puts the real cost of the oscillator at $500+
I have a small collection of 10811 and similar oscillators here, collected
from hamfests rather than china (and mostly pre-ebay).
What sort of testing regime would you put them through ? I don't have
anything as exotic as a timepod but I do have an HP53131A, the Tait Rb
source, and a KS-24361 set
Hi
It is *much* better to have an OCXO that you do not need to test to death.
There is simply to much testing to do. A modern factory does not test the
quality into the product (of any sort) they design in and build it in. The same
is true of the normal customer for virtually any component. They
