[Elecraft] KPA500

[David Olean]

Thanks all for the comments. I suspect the amp got hit with excessive 
power and blew out the PIN diodes. The bias current of 0.6 amps is 
telling me that the FETs are OK, but no change in Drain current with 
drive tells me that the switch is NG.  Why did I ever loan it out. Live 
and learn.
