Re: MOT, and doubler

Thank you, I realized that after seeing the schematic on the inside wall of 
the microwave case. What made me realize it was that there was a bleeder 
resistor in the schematic but no external one. Then I realized the diode 
could be attached to the capacitor case. I wanted to try using the magnets to 
blow the arc upwards in a jacb's ladder so I hooked my diode string up so the 
arc would go only one way. The transformer didn't seem to operate properly, 
then the fuse blew. I think the primary might have a short in it. :-(
