Questions about tubes and gear that glows. FAQ

Hi people,
Here's a link to a tube stage I intend to build for my pioneer pd-s 703,
http://www.ultranalog.com/cdenhancer/cdenhancer2.html
Here's the schematic, http://www.ultranalog.com/cdenhancer/cdenhancer2_3a5.pdf
I live in the UK and on some investigation, I have managed to find stockists of the tubes, and output transformers (sowter).
However I can not seem to find a required mains transformer to provide the exact 100v outputs for the circuit. I do know that maplins do have mains isolation transformers which provide around 115v, perhaps I could use one of these instead, and drop the voltage with a resistor???
Or does anyone know of an off the shelf type which is suitable?
I ask this as it may be cheaper than having a custom tranny wound for me.
Also the 4H choke, does anyone know of a stockist in the UK, Sowter does have them but not at this value which means I need a custom one, this might be expensive?????
I do know that Maplins have a 10H choke which is quite cheap, and if possible I would like to use this.
Just thought I would ask more experienced people before making assumptions on how to get the correct rail voltages and filtering by using substitute parts.
I am reasonably confident I can do this, I have built SS kits before, and can now read schematics well enough to understand how this links together.
Thanks
Raju
