RE: Opinions on 6P3S for Hi-Fi ?

An often-overlooked solution is to go with 12V6 instead of 6V6. I build from scratch, my own designs, and I use 12 volt heater circuits because it is easy to rectify and filter and, after the circuit is loaded down, it comes right in at 12 VDC or maybe a fraction of a volt over every time. This does help reduce hum.
NOS 12V6 is every bit as good as NOS 6V6 but WITHOUT the hefty price tag. you can still get NOS 12V6 all day long. The Conn Organ ones are usually black plates. They are simply rebranded tubes. So, you have options.

When I stated "as I recall, i used 35 ma per tube," that was the last amp I built using them, and I did use a higher B+ than I would have liked. I think that is why I ran them at 35 ma. I THINK on lower voltage B+ I used quiescent current in the low 40s. It's been quite some time, so details are a little fuzzy in my mind. I haven't played with them much in the last 3 years or so.

I have branched off into screen drive with sweep tubes, and that is more forgiving of high B+.
