[Elecraft] KPA-500 270V ERR

[Chuck Chandler]

My KPA-500 has been running great for several years.  Recently I noticed it
was making the occasional extra "click" or "thunk" upon powering up or
down.  Usually it would "click" when powered up and again when powered
down, but recently a few seconds after the first click there would be
another one, maybe more of a thunk sound.

This afternoon I turned it on and when I pushed the Operate/Standby button
I got a fault light and the 270V ERR message on the display.  The menu HV
option shows 68.4V, varying a bit, on my 240V line.  I put it on the bench
and opened up the top cover.  There is a smell of overheated components,
maybe burnt but more like too hot.

I've submitted the contact form on the Elecraft support page.  Any
suggestions?  For now, I'm running barefoot...
