Very nice Paul, have you put it through the ringer regarding mismatch,
open, or short.

I don't know how the freescale parts are, but the NXP BLF578XR seems to be
holding up well for me. with 4 watts I can drive it to about 1450W output with
52V @ 42A. I've been running it ~45% duty cycle 45s on 75s off with wsjt on 2m
without issues.

John, sounds like a great commercial project with quite an end result
most Hams will never see. I am very curious about your testing.
Be very interested if you had any fault history for the MRFE6VP61K25H.
Have you pushed it to extremes.
