Hi!
I need some help on this.
I want to make my own O/P transformer to tube amp.
I've searched a lot here at the forum, at google, and some other 'portals'.
I still not have the infos I want.
So:
- Formulas;
- Windings (how to);
- Cooper diameter;
- Etc.
I know that the best is to wind p-s-p-s-p... portions in layers.
Thanks in advance for any answer.

I have posted this before, but here goes again:
This document prepared by Craig Ryder is an excellent resource for links to almost anything to do with valves!
There are many good transformer references in there - I've copied them below:

Hi all,
ok, if anybody wants this document please PM me and I' ll send it per e-mail. It' s a rather large doc, and can' t post it here on the forum, due to size limitations of the attachments.
The link I provided links to my Yahoo briefcase, where I posted it temporarily.
Cheers,
Bruno
