[ARC5] [Milsurplus] I Must Have Lost My Mind...

Needs a feedback loop to regulate the output.  Might be an interesting project, but the VFD is easy, and you can have a great deal of protection for the equipment you are running.

400W class D (swigching) audio power amps are not hard to find. Audio oscillators likewise.

"Unobtainium 800 cycle inverter possible."

 

Has anybody created use-able 800 cycle power other than by motor-generator? 

Maybe aviation maintenance equipments? 

A high power audio amp with a 555 oscillator? 

Frequency Doubler-Double-Doubler high power diode circuits?

 

A couple of AN/APA-38 Panoramic Adaptors (30 MHz) would like to know...

It's a Westinghouse GO-9 U.S. Navy Liaison transmitter, circa 1940.
100 Watts out, CW Only, runs on 800 cycle AC like the later GP-7.  |
On the left is the Power Supply, 2000V and 500V.
On the right is the High Frequency transmitter module, 3-18 MC.
Missing to the left of the power supply is the Longwave transmitter
module.   Often installed in pre- and early-war PBY patrol aircraft.
Most PBY Radio photos you find at Google are from later, with 
the AN/ARC-8 installed.

Good overview on Mike Hanz's excellent site:
