Light Bulb Tester

At the suggestions of Norman Braithwaite and David Poland I increased the wattage in my light bulb circuit that I am using to power up the Philharmonic power supply. Both lamps (bulbs) are in series with the plug from the radio power supply. This setup caused all 6 power supply / amplifier tubes to light up. Previously none would light or just the 6L6 tubes would come on dimly if the 5U4 rectifiers were removed.
