You’ve hit upon a great way to basically keep the plate voltage and cathode
bias circuit stock and yet reduce the static plate current…..drop the screen
voltage. IMO the weak spot in all those commie 6V6s is the damn screen grids.
Try about a 2.2k (or maybe even larger)–(at)–2 Watt resistor in series with the
6V6 screen. If the value here gets large, you may want to add another filter
cap from the screen to ground, about 10 uf would be plenty.
