This config is worth trying to test if the series resistor has a positive impact in the sound!

For Rod's filament supply, send him a message. The schematic isn't public domain, but the boards are very cheap and he will give you all the details.

For Lundahl transformers, probably the easiest is to send a message to Thomas Mayer - see also his website. You are not too far away from him.

Which Lundahl transformer you need will depend on the ratio of stepdown you like, as he explains.

I don't know if anyone has details to hand of the posts that contain schematics - it's a bit of a trek up the North Face of this thread... I find it easier to message/email people concerned. Ale has all sorts of useful stuff on his site, but like Thomas's site the blog is turning into a very long affair also!!

Incidentally, I have some unused new in box Hammond 156C plate chokes, which are very good sounding wired in series - you use four for stereo. If anyone fancies using them I can negotiate on price and throw in some 26 tubes. I have a bit too much stuff at the moment. I'm in the UK. Andy

Great idea 12. Most the time, it is put on the first post. Not sure if the original poster is still active here but he could edit his first post and that could be the reference page.
