I used Rich Measures QSK system in a SB-220 and it worked just
perfectly. I never once regretted putting that in there and it was
definitely worth making.

That's not the setup I'll be using but, my reason for not using QSK/VOX isn't
related to any timing concerns. The new setup, along with cooling
modifications will make my SB220 quieter, even with the Dayton 4M070 motor that
Harbach sells for more $. The sealed relays will also fix the oxidized &
intermittent contacts on the OEM open relay.
Note to Jim: I should have the parts in hand next week.
