Cap in this position is supposedly improves the ripple by producing the opposite-directed ripple +90 degrees vs -90 degrees, so they cancel each other.
Its kinda counter intuitive.
The inductor alone is sufficient plus the cap in position 4-1 can be increased quite a bit without fear of damaging the 80 tube to have much better effect on the ripple.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
