Thanks Ian Noted on the caps, I put 100 as a minimum with the expectation of using a pair of 100+100 cans but it depends on what kind of chassis find, how much space there is etc. Currently looking for a decent shallow 2U aluminium rack enclosure that I can mount to the rear of for an old school approachSchematic looks basically OK to me. Nothing missing. I would be tempted to double the smoothing caps values. Heater elevation looks OK. It should sit at one third the HT voltage. I typically set mine at one quarter the HT voltage but one third is just as good.
Cheers

Also found an alternative power transformer here but I might see if they can do the same but with a higher rated heater tap—I was thinking about experimenting with the 6BX7GT at some point down the line but it's hungry on the current and wants 1.5A to itself. With the ECC83 it'll add up to 1.8A
