>From experience, I can tell you that you can't always depend on the seller when it comes to how to feed your new OCXO.  For instance, the seller of the Trimble 65256 insisted that it took 12V.  So, that's what I used, and all the magic smoke came tumbling out.

The reason that there was 12 volts on the unit was because I put it 
there.  I should
have tried 5 volts first but the only datasheet that I could find said 
12 volts.
All the eBay units that look the same say 12 volts.
