Matt,

Usually MOTs drive a magnetron, which delivers about 800 W to 
the food to be warmed.

>Its filament winding is only 3.18volts :-((((((((( I need 5volts
- Sometimes it is possible to remove some of the turns. So you 
could add another MOT with less turns to your existing one, if you 
cann't find a suitable filament transformer.

>Is the core the return?
- Yes, one end of the HV winding is tied to the MOT's core. You 
would like to connect the core to the mains ground for safety.

Take care!
