[Elecraft] KPA500 fault

[Ken Chandler]

Hi guys
While I'm waiting for Elecraft support to come forward with a suggestion, I thought I'd share my KPA500 (sn 0212) Amp's fault to see if it rings any new year bells with anyone...hi
Just be4 Xmas I started getting an occasional fault whereby the Standby switch would lock up, then after a few minutes another press of STBY and it would go Green.
However now it's locked on STBY and won't budge plus all the other press switches are locked out too like EDIT etc.
Other strange things are happening too, pressing tapping EDIT changes the band in the Amp.
In 2019, I installed the USB kit into my K3, previous to this I've fully upgraded the K3 to full spec.
When the K3 and Amp are both turned on the Amp senses the K3's current band setting, but everything on the Amp is locked up.

Appreciate any info or suggestions chaps!
