[Elecraft] KPA500 (S/N 82) Power Out Problem....

[W5RDW]

Last night, I turned on my K3/KAT500/KPA500 as normal and upon CW key up, all
the Power (W) LEDs lit up across the scale. The Fault LED was not lit. The
VSWR was good. The KPA500 reads 640 watts ?? Pout with nominal drive power
(15 watts) from the K3. The CUR is not reading any current. This happens on
all bands 160 to 6M. All was working yesterday with no problems. I took the
KAT500 out of the chain and ran the K3 directly into the amp input and then
the amp output into a high power dummy load/watt meter. I only read the K3
nominal power out (set to 15 watts) on the watt meter. 

I re-seated all the cables between the rig/tuner/PA. Has anyone experienced
this on their KPA500?
