Could be fun - been ages since I last wound a custom transformer >:o) Oh, for heaven's sake, why would you need a custom transformer? Step-up's are available in every shape and size from many places. Also, with dozens and dozens of 'old stuff' distributors in the US I'm sure you can find any type of transformer you care to immagine (www.alltronics.com, www.meci.com, www.jameco.com, etc, ect) >> P.S.

Hopefully, it'll be >quicker on the SuperIDE :o) Fraid not, at least not for a while. Nothing to do with xxxIDE, but with the speed of the QL's 8-bit bus. The peak bandwidth is only 1.8MB/sec and even a bit less with GC/SGC. All of this really to cater for the 8301 video ULA. Even with Aurora, which is capable of about 5.5MB/s things get stuck at 1.8 because the GC/SGC deliberately slow down when communicating through the QL bus, just in case there is a 8301 somewhere - even if it's in the spare parts bin :-) GF's IO protocol is software-customizeable, and can push the 8-bit bus very far (probably too far) - in theory, up to 12MB/sec but that's still only ATAPI PIO3 or so, IF signal integrity on the bus remains sufficient.
