Looking at the schemo, I guess sometimes there are actually good reasons why certain solutions to common problems are popular. Meaning, I ass-u-me you have the noise consistently down to acceptable levels with the split-type L, etc., and no more runaway voltage.
I think I would still opt to de-solder the unused tube grid, plate and filament/cathode connections when not in use, just to be on the safe side. Not being a tech-whiz, I don't know but only wonder if added wire on those lines would increase effective capacitance, in addition to the energized-wire-as-antenna problem?
Anyway, if you wound up with a truly quiet D-C 2-stage DHT with AC filaments, congratulations!
And now you get to integrate it!
