Output transformers will be fun for valves never intended for audio use. I know how to do the numbers, but really it's more a case of doing it all on paper, then running into a dummy load and seeing when everything smooths out.
I have changed my opinion of valve power output stages over recent years. Now it's easier to run from individual isolated heater supplies and run on a split supply as used in totem pole transistor/mosfet amps. Thats just a matter of personal taste for me as big expensive lumps of ironwork are to my eyes impractical for new build gear.
