Hi Tom,

I used 750VA, 2x24v in series (close Clive, I know some use 2x25v but I think it tipped the voltage a bit high once rectified and smoothed etc. ? Can't remember. I get 72V unloaded so OK with that.)

Toroid from Airlink transformers:

Read post #42 onwards for the Toroid/PSU development, and read post #70 for the 'final' wiring diagram. . .

Note that I went with the 10A Type D MCB in the end as the 6A tripped out on startup due to the inrush current (no soft start). It's been running fine since.

Thanks
