So the original 2-section electrolytic cap had the red and orange (+ leads) going to pin 4 and pin 8 of the rectifier 35Z5 and the common black lead going to B-.

All I did was dump the original and install 2 20 mfd 160V electrolytics and run one + lead to pin 4 of 35Z5 and the other + lead to pin 8 of 35Z5 and ran both - leads together to B-.

That's the way the radio was wired originally.
