Why 50+50 can caps in parallel?

Post by Xander8280 »

Marshalls tend to use at least a couple canned caps with the pairs in parallel. Why not use a 100+100 for each 50+50 application?

I understand that some run a 10Kohm resistor between, that is different.

Does the fact that the canned cap halves filter differently together than a single equivalent capacitor?

I'm looking to start a build and it requires a lot of canned caps in a tight chassis. I'd like to understand more about why 50uF is the go to filter cap for jcm800s, would higher filtering neuter the amp?

Maybe it is to gain more voltage headroom to prevent frying the caps if there are any voltage swings?

More about separating the grounds, I think.

Separating the grounds plus bulk quantities of LCR that fits everywhere in their old projects.

Is the common ground within the can that much different than the grounding bus the negative leads all connect to? What would happen for A and B+ sharing a 100uF+100uF?

Thanks guys!!
