  • Stupid question---

    Been sick for 5 days and cant focus here---stupid question...

    i think the answer is no---shared ground on my can caps .

    ive got a couple 100/100 uf/500v can caps here i was going to use in this old 2203 Marshall--but it looks like i cant due to the shared ground of my caps --see the "four" 100uf filters ?----i think i need 4 separate caps.

      Yes, the four 100uf caps need to be separate, and make sure the neg terminal of the upper ones are not grounded.


      I have seen series can caps, but those are rare.

      It is the common ground that is killing you. A common 50/50 would only work for the ones up along the tops.

          That is not a stupid question. There are some non standard things going on in that schematic that did not endure.
          It's weird, because it WAS working fine.....
