[Amps] Microwave Oven Power Transformer

[Steve Thompson]

Doubling up does solve the flux problem, but means a lot of 
resistance - MOTs usually start with high Rs for their rating. 
More transformers in parallel can compensate so size is then the 
downside.

Normally, 10 or 15% reduction in volts is enough to bring the 
magnetising current down, so rewinding one to work as a 'buck' 
feeding 4 or 5 others is another option for the thrify types.
