Low Filtering Question

Post by stav92 » Sat Nov 17, 2018 2:40 pm

I'm trying to design / spec my own Modded 12xxx series Marshall style amp but I'm a little confused about the Filter caps.

So I really want to try 100u + 100u in series at the mains supply for 50u Total, and 32 + 32u in series at the screens for 16u total (and a 50u PI cap)... This is for a saggy 100w Non Master volume build.

Is it not possible to wire Dual can caps in series with themselves ?? I was under the impression that the whole point of Dual electrolytic caps (100/100, 50/50, 32/32) was that we had the choice to wire in parallel or series to save space and number of caps.

A friend of mine the other day told me that you can't wire a Dual cap in series simply because the ground terminal is shared between both halfs of the cap ... I was like WTF, this whole time I've thought it was that simple. :palm:

Is he correct? If so, How do all of you guys get your low filtering without physically drilling extra mounting holes and trying to make space for 4 Huge Single caps?!?!! Couldn't it just be as easy as wiring a dual 100/100 and a dual 32/32 ? haha

Sorry if this is a really dumb question . :stars:
