Someone suggested running B1 at 22V so I'v got a straightforward LM317 reducing the 25V from the CRC down to 22V. But to be perfectly honest it runs silently and perfectly at 25V from my basic PSU.

Nelson's original B1 only used a Wall-Brick and the on-board 15000uF 1R0 15000uF gets rid of any noise.

I wouldn't recommend an SMPS wall brick.

Yes I'm using 9-0-9 as a single 18V supply which is then rectified which gives about 25V after the caps.
