Well I have some 450V caps but the original design used 500V Electrolytic caps. I do not have any 100V or even 50V caps to put in series. I was hoping to reform new 450V caps with a surge rating of 500V to work properly at 500V's. The original circuit used 10mfd 500V caps. I have 100mfd 450V caps on hand. I already am grossly exceeding the 80% rule ont he capatence side of things. So I would prefer not to have to buy more 450V caps at a lower rating and need to put in 100V cap in series to bring the entire thing up to 500V. I can I was just looking for another solution. I hateing buying more cap's for something like this because if you have nothing else to order at the time the shipping kills you!!! I will just have to wait longer to get the unit on the air.

The problem is that the Corneil(sp) Dublier Paper Cans are huge and they have fuzzy paper blister's on the end caps. So even though the unit powers up fine and work's it is only a matter of time before these two 500V 10mfd caps go bad. They are int he main power section just before the voltage rectifier card so kind of important caps to have functioning properly! I do not think it would take out the tubes if one of them died since their are caps after them and a boat load of diodes but I prefer not to risk it!

Thanks for the link and the advice. At this point I remember just enough to be dangerous....LOL
