One thing leads to another. I was checking some of the caps for leaks, shorts, and grounds; and I noticed that I've placed a 630v cap where the voltage is supposed to be 680v. I've run the set for quite a few hours with no problem. I suspect that the actual voltage is higher than 680v, but my multimeter doesn't go above 600v.

So I have two questions:
1. Should I replace the cap with one of higher voltage rating? The only solution I have on hand is to use two .2uF/630v caps in series. This is in a two-cap bakelite block, and I can squeeze three caps in if I'm really careful about shorts.
2. To check the actual voltage on the (specified) 680v line, can I put the transformer on 60 VAC from the variac and expect 340 volts?
