I have this dislike of pentode screen grids at higher HT than the anode by being direct onto the HT line too. I think a screen feed resistor with a 100nf decoupler is a better bet.
I was surprised that the reservoir and smoothing caps were so good, they check out very well against new parts. Course its a resistor smoothing, no choke.
