Fets are cold in normal power idle, fets get very slightly warm in half protect idle
DP1-4 read 0.33v at normal idle, DP4 and DP2 read 1.3v at half protect idle, DP3 and DP1 read 1.13v at half protect idle
Which pins are 10 and 11? (Which side is 1 so I know for future reference)

What's the rail voltage difference at normal idle vs 1/2 protect?
Post the voltage on pins 10 and 11 in normal idle and 1/2 protect.
For most of these boards, pins are counted left to right on the side where you can see the curved part of the header pin that solders into the board. It's +F and -F.

DP1-4 (voltage regulators) read 0.33v at normal idle
DP4 and DP2 read 1.3v at half protect idle
DP3 and DP1 read 1.13v at half protect idle
F+ reads 2.46v at normal idle
F- reads 2.46v at normal idle
F+ reads 2.45v at half protect idle
F- reads 2.47v at half protect idle
When reading F+ and F- the buzzing near the transformers would stop (normal idle)
Buzzing continues when meter is removed
