Scott,

I suggest you usolder one  or both of the wires going to the crystal  
oscillator heater.  It sure sounds to me that the thermostat is stuck  
shut.

It should be simple enough to see if the OVENS switch is working or if  
it is stuck in the on position, too.  Most folks turn that switch OFF  
(it's on the back of the radio.)  That should remove power from the  
PTO and the crystal oscillator oven heaters.
