Toroidal Transformer

[Carlb1058]

Okuls - a touch of clarity, should have done this to start with.

The Chinese controller went tits up, turned out it was the spindle/stepper controller board which was replaced under warranty. When they sent the replacement, attached to it was a spare IRF 630 (from mem) chip which meant I could fix the original as well (bonus).
Now when I was putting together a better controller with the M542's and a bob a PSU was required so I bought one off eBay but couldn't for the life of me work out where the spindle went, a post here told me I need another PSU to run the spindle.

I honestly can't see the logic in running two PSU's so thought I'd make use of the original (now repaired) spindle/stepper controller board and just buy a toroidal the same as what's in the original controller box, which meant I could still knock stuff out with the original while fiddling and fine tuning the new controller box.
Unfortunately, I've found one only company willing to even consider it here in australia and until I can come up with exact specs they won't even bother starting but they 'are' willing to price it $150 plus shipping which is what ₤90 plus shipping.

The attached pic is the basic idea, the 24v to the M542's will obviously be split for three + and three -
