If I'm understanding things correctly, I should be getting about 305 between the center tap, (the red with the yellow stripe) and either one of the red wires, what I'm actually getting is 770ish. I removed it from the circuit to make sure it didn't have anything to do with my wiring. I started investigating because I was getting over 500 volts at the first filter cap. This is the transformer I'm using. http://www.classictone.net/40-18021.html Thanks!
