I picked up a couple of inverter powered microwave ovens at the goodwill
and I was wondering if these power suppies can be used wih tube amps and
such. Also would like schematic data if I could so I could see if I can
modify them for other voltages besides thosed they are designed.


I didn't know such contraptions existed Please post brand name, model
and nameplate information from them to permit a bit of research. Sounds
like a candidate for the quad 807 linear awaiting a power supply...

Cant get to them right now for more data but one is a Sharp and the other
a Panasonic.


i have found that they are regulated and variable to some degree via pwm Old
stle microwaves varied power by varying the duty cycle that the tube was on
over a period of seconds. that is to say if a 705 power was set the tube
would be on full power for 7 seconds out of 10. the inverter style actually
decreases the voltage to the tube. interesting possibilites about for
amplifiers
