Dwight... Without a "theory of operation" manual and a good schematic,
it's really difficult to tell what would cause this. I'd like to see
Elecraft publish an addendum to assist troubleshooting this amp.
Would a defective interlock switch cause this or a loose circuit board
plug? That would be too easy. 270 and 60 volts run to the PA assembly.
You would have to isolate the PA assembly from the power supply for
troubleshooting.
Give Elecraft a call and they will help you out!

I'm getting this error from my amp when I turn it on and set it in the
OPER mode. Then it requires shutoff via the rear switch to shut it
off. I've been running it off 120v and has been working fine.
What do I need to look for?
