It is information like this that maintains my interest in amateur radio.
Are you interested enough to build one?
My guess is that 6 of the Panasonic switchers would power an 8170 in SSB-mode, especially if an energy-storage C bank was connected to the output and the units were powered from a 50A electric range outlet.

Very interesting Rich.
What would be the regulation of this switched mode power supply?
Cheers, Dick

I purchased one unit from Costco. The price was $99. The unit was
surprisingly light in weight compared to my old transformer-
powered
400W u-wave oven. I found no RFI problem from 50 - 550 MHz. The
rating is 1300w, which is most probably the DC input power to the
magnetron. At 120V, c. 17A of current is drawn. If a SSB amateur
radio amplifier was built using the Matsushita switcher PS, two
units
are probably needed. By putting the 120V inputs to the two
switcher
supplies in series, operation from a standard, 240VCT, 20A outlet
would work. I have not yet disassembled the oven to measure the
HV.
Does anyone know what's the typical range of potentials used to
power
magnetrons of this size? tnx
