OK. I have a 22k (runs at 18k TPO typically) solid state FM Broadcast 
transmitter. So far I've only seen this brand in LPTV / TV Translator 
useage.
 
It's been a good unit, until last week - the 250w exciter went dark. 
Micro / synth failure. To be fair, we had an air conditioner problem 
last year that probably stressed everything. So the Exciter is off to FL 
for service/ check.
     This TX has a 250w exciter, split 8 ways so each of 8 amplifier 
drawers gets 30w max. Each amp drawer has 8 transistors, each with a 
separate 48v switcher supply. So 8 amp drawers combine to get full 
output. Any drawer fails, you turn off it's "mate" on the combiner (to 
reduce reject load heat) and keep on running until you can shut down. 
    All power supplies are monitored, so you can see volts/ amps/ per 
transistor.
