Update on my low output issue:
I ran the TX Gain Calibration this morning, and everything passed with
flying colors.
I am seeing about a 4-4.5V drop across the radio when going from rx to
tx. Rx voltage sits at 13.8V, but when I transmit, voltage across the
rig drops to between 9 and 9.5V.
All tests performed while tuned into a 300W dummy load.
Before I tear into my rig and start looking for corroded tin pins on the
PA board (K3 #281, so unlikely the board was replaced/mod performed), is
there anything else I should test while my station is still all together
in one piece?
Thanks to everyone for the assistance, and Merry Christmas!

Chuck,
It could - defer decisions on that until after doing the TX Gain
Calibration.
