Charles, at 100w into a dummy loadI see a .8 volt drop from 13.8 vdc on
a switching supply, and 17.5 amps. I think it may be time for me to
clean some contacts, too. The fuse holders are always good suspects.

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
