Re: removing MOT shunts

JW,

The MOT shunts aren't nearly effective in a MOT as NST shunts are in an NST.
In a microwave oven, current is partially limited by the shunts, partially
by the series about 1 mF cap, and by the nature of the load (magnetron).
Your 720 watt MOT can put out considerably more than 720 watts as is - no
need to knock out shunts.  I suspect if you short the output, you may trip
your circuit breaker or at least have a smoking hot MOT, whereas if you do
the same with a NST, which is what conducting neon does approximately, the
NST shunts keep the current limited and the NST doesn't overheat.

If you do use your draw 1.1 kW out of your 720 watt MOT, then you need to
worry about cooling it, such as submerging it in oil.  Probably easier to
find some more larger MOTs.
