Completed recapped. All caps were replaced save for the “black beauty”. After recapped all voltage was on the dot (according to the schematic) coming out of my wall outlet.

Currently have a quad of near NOS Sylvania 6L6GC (tested about 95%+ on my TV-7/U; 38, 38, 36, 36 with 25 being minimum good). Small tubes are mixed of vintage tested good tubes.

Have been playing without problem constantly for a week.
