Good point, I'm assuming that the tube rolling doesn't include anything more than a bias adjustment. To lower 45 Rp you're going to eventually run into max dissipation. I imagine you could keep lowering the plate voltage until you lose your ROI.
Sounds like more than a tweek and roll exercise...
My problem is that my most efficient loud speaker drivers run around 90 to 92 DB / watt....so exploring 10k primaries is a something I will have to wait for....
