Hi Andreu! and welcome Re: Bron yr Aur Stomp's tabs, there's another thread a little below yours which mentions some tabs.... Alfred studio notation/tab version. Just take a look at that thread. It might help a little bit. Since one of the posters there mentions that Jimmy Page uses some Chet Atkins riffs, get ready for some jazzy chords. (But then again, he (Atkins) used EZ chords like E7, too ) I'm sure you'll do very well!
Edited to self-correct: Jimmy Page uses the Chet Atkins riffs in the DVD live version of "Bron yr Aur Stomp" (Earls Court '75), not the studio version. That, like the guy said in the other thread, is the longer, extended fantastic solo.
