I've never seen a PDP11 or PDP8 with a power supply

IIRC, adjusting the PSU regulators to be slightly higher or lower than
+5V _is_ mentioned in some of the service manuals as a way to trace

The PDP-5 has a big knob in the back to turn the power supply up or down
and a whole procedure for finding weak transistors in the maintenance manual.
