Tom -
I had the same experience a few months back. I talked with Elecraft Support, and they had me check a few things. There was no obvious cause, except the power supply board was dead.
They asked me to send it in, which I did, and they replaced the board. Fortunately I got it back a couple days before the COVID shutdown hit, and it has been fine since.
As a precautionary move, they changed the power transformer back to the default setting. I had set it up one notch because our line voltage is low, and that was needed to get it "near" the optimal value.
I also have tuner (KAT500) issues, but will live with it, as I am reluctant to send anything anywhere at this time.

Subject: [Elecraft] KPA500 Dead
I was operating on FT8 20 meters for quite a long time with my KPA500
running about 400 watts and heard a few pops (like something arching).
Heard it a few more times then the amp went off.
Now it will not power on. No lights, nothing. I checked the fuse and
it is OK.
Can you tell me where to start looking?
Thanks
Tom AAA4VV
