So, I'm confused. Part 91 is a two section electrolytic cap which should be 8 or 10 mfd. Your photo shows a three section cap and I'm not sure your numbers 1-4 are for the wires or the terminals. If the third section was wired in, the schematic isn't useful since I could not find another 20 mfd cap. Did you number the wires you cut? If so you will have to tell us where they go. I can see that two of the wires were attached to the common terminals of the can. When you say center tap are you referring to the audio interstage transformer or the power transformer?
