David,

	Sure appreciate the explanation!

	I don't have an immediate need of that sort but now that it's out there
maybe someone on the list does.

	I'm guessing the usual street price of those is much higher.

	Meanwhile, I have a 6kw 240v inverter and a similar capacity
transformer/phase converter that need a new home - perhaps someone
at Hamcation will have a need ...

Thanks again - David KD4E
