Update on the k150-8 project.
With all boards installed normal, I have 89.3.vdc at the power iputs of the board. Voltage at the preamps is 9.5v on the red/positive side, and 3.87 volts on the negative.

With the power cut off the right preamp it is 10.62v positive and 2.76 vlots negative.

With both preamps cut off it is 12.56 volts positive and 1.4 volts negative.

Looks like I have a power regulator problem, too.
