Connect a light bulb in series with the 120 volt line and power supply. Say
60 watts. The large caps you can estimate their capacity by seeing how long
they will light a small lamp after the supply is turned off. (12 Volts for
the +8Volt line, 24V for the +/-18 volt). Or you can time the discharge from
the bleeder resistors.
