I'm working on rebuilding a SB220 and ordered the ES4SB220 from Harbach in bare PCB form to replace the filter capacitor block. Last night I tried to install the board, but I can't get the rectangular bracket in place over the plastic spacers. The screws don't make it through the bottom holes and no amount of pushing on the bracket seems to help. Based on recommendations here and my own measurements, I used the following CDE cap: 381LX331M450A042. Diameter is 35mm which is what the openings measure so I'm really confused on why this isn't working. I'm looking for advice on enlarging the plastic capacitor holders to fit the new caps better, or on what to try to get them to fit as is. Thanks for the help!
