Re: Overstessing Maxwell caps

Hi Steve,

It's really up to you. Obviously, 3x is safer than 2x. It's one of things
where it only takes one
time to kill the caps. I don't think anyone can say go with 2x and
everything will be ok, or go
with 3x and everything will be ok. It's ultmately your coil and you have to
make the decision to
chance it or not.

Regards,
Bart
