Larry - I didn't. The 250 watts is produced by a GE MASTR Pro/II 4EF5A1 capable of 330 watts continuous. The MICOR high-band tube amplifier, IMHO, is junk compared to the GE 4CX250R based VHF power amplifier. The 4EF5A1 is designed to operate from 144 to 174 MHz. without modification. Obtaining proper drive for it was the fun part.
