Besides my earlier direct email to you Greg, changing the sb-220 120v FT supply to a FWB rectifier and replace the C4 electrolytic with a 200uF to 320 uF works very well at speeding up the existing relay. The much larger capacitor can be sourced from a good one from the HV capacitor bank when replacing bad units. The FT supply handles the much larger capacitance with no issue.
Circuit see right side : http://www.somis.org/add-160m-d.jpg I have 3 sb-220's here, One has a AG6K qsk kit fitted which works very well. They all have FWB rectifier (relay)supplies and 450v/320uF electrolytic's which fit snug between the deck base and lower side rail @ 35mm diameter. Just silicone in place.
