[Elecraft] normal K3 voltage drop on TX

What would be a normal value on the FP voltage display when tx at 100W,
using factory fused cables? No sub installed.

PS is Astron VS-35M linear, voltage set at 13.9 idling per FP display.
drops to 11.1 on TX.  Current varies but up to 15.5A indicated. Specs call
for 17-22A tx @100W.

I suspect bad pass transistor and/or high drop over fuses, but want to
establish normal indication for tx drop.  11.1v seems way out.

tnx in advance
