Hi All...

another thing to watch out for in the so called near future....     MOTs 
are being replaced by PWM ( pulsed width modulated) power supplies... yes 
they are smaller, lighter, more efficient?, cheaper? ( must be
they are replacing the older models with Xfmrs rather quickly)   we had a 
MW at work go into the "non working status" ( we have several MW at work in 
the break rooms) soooo... being in the R&D dept. I had first dibs on 
it...  after removing the shell I found no transformer, diode, and cap, but 
a conglomeration of inductors, mosfets, and voltage multipliers...  along 
with several IC chips ...   no longer are we given the simple objects of hi 
voltage ( Xfmrs, caps  and diodes)  from MW ovens but instead...   hi tech 
electronics that will challenge the intellect of of us without the EE 
degree.....

start reading up on AC to DC pwm power supplies people ....   looks like we 
are in for another learning curve...
