You are right, the voltage is the same. I hooked it up the standard way and got the lower voltage again. The only other thing I changed was to put two big 40 mf oil caps in place of the twin 50mf 'lytic I had for filter caps. Could they have dropped the voltage that much?
In any case, I guess I will still go ahead and build the separate power supply and see if I can get rid of the hum.
