I have an interesting problem here. When connected in the prescribed way, the 8uf Electrolytic pops when powered up.... bulge and puff of white smoke kinda stuff. I have the 8uf side connected correctly..... (+) side to to the Rectifier Tube(pin1) and GreenWhite Speaker wire, Negative side to the CenterTap.

I am using a 450v 8uf Cap.... Given the amount of voltage that can come thru here on power, I am wondering if I have to go with a 600V cap instead. Has anyone seen this before? Perhaps a bad (80) Rectifier Tube ?
