I did use a toroidal on the off board 20v heater supply for my GM70 and B++ for the 12GN7 driver tubes but that was on a whim. I used a custom air cleaner cover from a Harley to hide it.
I also included a pic of the chassis I made for the compactron amp.

Hey djn!, if you like the results from adding a series resistance to a cap-input filter, you will LOVE the choke-input filter...
PSUDii is quite good enough to show the benefit you are seeking.
For a diode, examine the big damper diodes. Their only 'cost' is in heater power, but that is just a bigger heater transformer. Two 6CJ3 in || on a full wave will take the load to near 10A...no biggie. Just get a bigger air cleaner cover. S&S?
As to a schematic, examine the Ford Audio Club newsletter from 2020 where my son wrote up the construction of a 6AH4 linestage that delivered ~30 Ohm output Z...
