I've never opened an OCXO but I have opened several sealed HV power supplies used on HP 5061A and 5061B CS Standards. These supplies are mounted by four 6-32 screw studs which make for easy 'holding' in a lightly tightened vise. I used a very focused hand held propane torch to go around the very base of the supply while grabbing the top with a large set of slip joint pliers and applying a gentle lifting/rocking motion. You have to heat up the entire circumference but it doesn't take too long and there was never any internal or external damage. Very easy to reassemble in the original configuration as well.
I also remember a thread several months ago about opening a Morion MV89A OCXO to repair a loose solder joint on the output. I don't recall what their method was but you should be able to find it in the archive. I think it, too, was an 'unsoldering' approach. Hope this helps. Good luck.

What's the best way to open an OCXO in the typical solder-sealed tinned steel can? I don't mind destroying the can itself, as long as the innards are not harmed. The goal is to run some experiments with thermal impedance as discussed here last week, and to ovenize parts of the EFC controller for better stability.
