[time-nuts] 5MHz ocxo

[Ron Ward]

Hi:
If you want to de-solder the case, I have had success taking some #12 or
#14 bare copper wire ( standard solid conductor house-wiring stripped of
the PVC insulation ) and wrapping it tightly around the base just above
the soldered junction. The wire is installed in my soldering gun just
like a new soldering gun tip. Add just a little solder to help in heat
transfer. Be careful as it will get really hot. I hold the top with a
weird set of very long needle nose pliers. They are small enough that
they don't act like much of a heatsink. You could fabricate one out of
wood. They would be disposable.
I hope this helps,
Ron

Apologies for slightly poor quality.

It's fully soldered at the base - possibly wasn't done in one go but I 
suspect would all have to be heated to get it apart - I have an SMD 
style hot air gun but it couldn't tackle that job.

If anyone is able to repair it I'd certainly be interested.
