Additionally, the outer heater on many commercially-available "double 
oven" OCXOs -- including the DO 10811s -- is not on during normal 
operation.  It is only there to get the inner oven up to temperature 
quickly, then it cuts out.  This allows the inner heater to be 
designed for lower output and finer temperature control, without 
taking forever to warm up to operating temperature.
