You’ve done a good job there Andy! it’s given me the boost I needed to get on with mine.
I tried doing my build slightly cheaper and ordered an R-core transformer from eBay. I couldn’t get the correct voltages from it neither could a friend who builds his own amps etc. It put a right damper on it for me and I gave up but He advised me to contact the seller and ask for a refund (I did) Now I have a refund I’ve just ordered a transformer from Toroidy.pl so I could do with getting on with the rest of it before it arrives.
Glad it's up and running mate. Enjoy!
