OK I understand the parallel caps adding to a higher value but when you say the 2nd cap, I really don't remember which of the 20 mfd caps I installed first - the one that goes from pin 4 to B- or the one that goes from pin 8 to B-.

Should I just pick one of those 2 and put another 20 mfd across it?
