Bill,
I'd do the resistence checks shown in the KPA100 manual under Alignment and
Installation. It's page 40 in my old manual. Anyway it's Q1, Q2, Q9 and D13.
All the final and driver circuits.

Subject: [Elecraft] K2 - KPA100 down again
After performing flawlessly for over a year my KPA100 has died for the
second
time in about 3 months. I was finishing a nice 20 minute QSO on 10M CW
last
week when the rig's lights flickered and the power supply shut down. Now
the power cord fuses blow and there appears to be a short when the power
supply is turned on - even with the rig off. The K2 itself is fine and
works great QRP but I need help with what direction to take with
diagnosing
the KPA100 trouble.
May be the KPA100 is upset that my K3 will be here in a couple of months
and
it and the K2 will no longer be center stage in the shack?
Any and all help greatly appreciated!
Bill NZ0T
