Re: [TCML] Different sort of MOT

Paul,

Sounds like you've opened up one of the newer
type microwave ovens, with the inverter high fre-
quency (probably something like 10 to 20 kHz)
power supply. This allows for a much lighter de-
sign but, like the newer inverter type of NSTs, it
is also pretty much useless as a power source for
a Tesla coil.
