I've been searching for an Atari colour vector power supply with no luck, so it's time to go a bit Heath Robinson. I've a spare Atari raster power brick (Centipede cabaret) that'll give me most of the voltages I need. But I'll be short of the 50V AC CT for the 6100. But I'm fairly confident that I can splice one of these into the brick:

This gives 48V AC CT, which falls slightly short.

However, the 6100 manual indicates that it'll run with up to 15% less:

So I should be good to go.

Only one question - 6100 manual suggests input power requirement of 150 watts. Any idea if the transformer above will meet that?

They come in a range of VA ratings, and if V*A still = watts, it looks like the WBPT150-24 would be the one for you, or maybe give yourself a bit of leeway with the WBPT200-24. Let us know how it turns out!

VA does not refer to V x A, but voltamps. VA = W / PF (power factor).
 
Thanks Dez.

I might go for this:

This would give me 2 x 25VAC. But what would I do about the centre tap? Presumably the power input to the 6100 wants 25 0 25. For the 0 could I just run a wire straight to/from any ground (most likely just tie it to the usual grounds on the power brick)?
 
Right. Think I've got it straight in my head now. The secondary windings would be connected in series to give a centre tap:

So ... from the toroid, red and yellow gives 25 25, tie together black and yellow for the 0 centre tap. Cool. Should work!
