All this talk about inverters, i went out in the garage to see what i had. Lo and behold, there is a "Class A Inverter, 100VA 3 phase, 27.5Vdc input @ 9.2 A, 115V @ 400 cycles output with a .95 PF" Sounds like the right one huh? Only a 3 pin plug on it. It sez: D-C - Input B grnd A-C - Output A-C - Grnd Ph. rotation A-C - grnd Nice shape and runs sweetly with that nice inverter sound to it. Larry W0OGH
