[Milsurplus] [ARC5] Navy GP-7 Transmitter Connectors Available

Joe,

The short answer is no.  The results of doing it wouldn't be quite as bad 
(or wouldn't be bad as soon) as running 400 cps stuff off of 60.  But in the 
end, the results would be the same.  You'd fry the transformer(s) and might 
do likewise to the inverter.

I still have a few of the PE-106-A's left if you want to go that route.  
But as Jack said earlier, they're actually a little shy of the KVA rating for 
full power out and as they were made to supply 80 VAC for Brit equipment you 
need a step up transformer.  Another possibility I've often thought about 
is the brute force method of full wave rectifying and then filtering the 
output of a 400 cps inverter.  Efficiency would be awful of course.
