Hello
Greetings from UK from a first-timer on DIYaudio. Hope that you're all well.
Duncan Munro, originator of PSUD2 and with whom I have corresponded now advises I advertise for help in the use of his model. (As an ex chemist it's not the mathematics of PSUD2 diode Vlaw and Vfac that is the problem. I fully admit I was using a 'carpentry' approach to understanding circuit design when I started out on collecting parts for this project ~ 10 or more years ago. I've not been well...)
Basically, the task would be to 'translate' an existing but long passed-over 300B PSU using a thermionic rectifier and discontinued (Plitron) chokes to Solid State rectification and current production chokes (e.g. Lundahl.)
If you've such experience as a designer and are willing to help and be very patient with me (clearly I do not want a lot!) then perhaps we could discuss terms to take this further?
All responses will be acknowledged / answered.
Many thanks.

Try Psud2 by duncan amplification to simulate PSU behaviour,
BY2000 or UF4007 diodes make a good choice for the SS diodes.

If you read the OP's post, he is in contact with Duncan. From other sources I know that he has a large collection of expensive power supply parts and lacks the confidence to just try-it-and-see, so is searching for consultant.
