Anyone ever use cap cans in series + parallel?

[plumcrazyfx]

I'm running out of space in my build.  I'd like to free up some space using a cap can.  Problem is I think I need to series them like in big Fenders with the 220k balancing resistors.  Problem is they all have a shared ground for the 2 caps.  Could I use 2 47uf cans- tie each of the two sides together in parallel and series the two pairs to get higher voltage rating?  This would end up with 47uf 900v right?

Yup, maybe, is the "can" part the same as ground, if so the "top" can will have to be completely isolated so it don't touch ground.  It will be like having a giant lead - live @ big volts

The ground lug isn't connected to the outer shell on JJ or F&T as far as I can tell.  I know they are on some CE Mallory types.

Lots of folks have done that, including Marshall.

I've done that with some older LCR can caps. Just because it has a negative lug/terminal doesn't mean the outer shell isn't also connected, so you should check continuity if there are any exposed metal parts. In my case this was a problem with one because the top cap was metal and "grounded" (negative) even though the rest of the "can" was plastic + shrinkwrap. With the others, the top was plastic too and there was nothing to worry about.

I will check it out.  I'll be using JJS in one build and F&Ts in the other.
