exactly.. I've thought about delidding a OCXO and cutting the trace.
That's a fairly expensive operation, maybe? (by the time we find a tech 
to do it, write the procedure, etc.)  It would turn a $50 oscillator 
into a several thousand dollar oscillator.  Still cheaper than designing 
a new oscillator from scratch.

Or if someone knows of an OCXO where the oven power is separate from the 
oscillator power, that would make it easy.

Darn these highly integrated parts..<grin>
