Power supply check

Checking the voltages on the PSU:

VoltageMeasuredRequirements
+12V11.875V11.95 to 12.05
+5V5.03V4.9 to 5.15
+7V7.038V6.9 to 7.1
-12V-12.10-12.5 to -11.5
-5V-5.01-5.2 to -4.8

The 12V is very slightly under spec, but I will leave it for now.

The PSU seems to be OK, but I’ll wait until I have the parts for a crowbar circuit to prevent repeating CuriousMarc’s adventures.
