I'm currently (finally!) in the process of re-building my ST-70. I am using one of the 80/40/30/20 @525 can caps for the power supply. I'd like to add more capacitance to the 80uf section (which will be used as the second section). I've seen folks use 450v rated caps here but didn't know if that was pushing it in terms of safety.
I happen to have some 100uf/450v Panasonic snap-mount electrolytic caps lying around and thought I might use a couple of those. The question is: do I run them in series to get one 50uf/900v cap OR can I run them parallel to get 200uf out of them even though the voltage rating is only 450v. I know the voltage rating of the second section is not as vital as the first but I don't want to push things...
Also, has anyone found that there is a practical limit to how much capacitance to add in the second section? Is there a point beyond which one is just 'gilding the lily'?
Thanks!
Joe
