[Milsurplus] [spam] Behlman AC power source?

[boeing377 at gmail.com]

China makes big sine wave DC-AC 50 and 60 hz 110 VAC inverters dirt cheap.
I bought one of the cheaper ones and have been pleased with its
performance,  I corresponded with the company and asked if they would
consider making 400 Hz versions and they replied it would be a very easy
thing to do, but there was almost zero market for such a device and
therefore they were not going to build one. I took the cover off of mine to
see if there was some way to figure out how to change the frequency, but I
couldn’t decipher the circuitry. The company politely declined to provide
any circuit information.
