My main concern though, is if it doesn't work first time, either through a faulty or damaged compoinent, or my mistake, I won't be able to fault find. And it seems rather odd that you can make and sell PCBs to someones else's design, but not supply the circuit diagram!
Well, at the the very beginning of the thread, I go into great detail about how the project came together.

It is the position of the circuit designer (Firebottle or Vivant on DIYaudio) wasnt happy to have his Schematic shared online.

There was a point made that someone could reverse engineer it, if they wanted to. Which I understand.

Anyway, the circuit was given to me "under licence" (of sorts) on the agreement that isnt distributed.

This has been upheld for 3 years and over 50 PCBs have been sold, with only two people needing any help at all.

Honestly, its SO easy to build this, if you follow the BOM.

However, if anyone does get stuck, or cant get it working, we have supported them for the cost of postage!!

I will talk to Alan and see if he is happy to share the schematic, but the choice is his....not mine.
 
Transformer Requirements are:
Primary should be local Voltage but UK should spec 240v
Secondary I - 165v @0.1A
Secondary II - 9.5-0-9.5v @1A

I use Toroidy.pl wherever possible
Looks very promising. Do you just send them your requirements for trafo or you can order a specific one through their webshop directly? Power transformers - Internet shop Toroidy.pl

I dont think he does the required Transformer "off the shelf"

I have always specified my needs and asked for at least 10" of wire from the
traffo, as they came a bit shorter than desired on the first one.

Sorry for the delay. I have just paid, and followed the instructions that were PM'd to me. Hopefully all is good with this.
