LA3a T4 autoformer info

[Aleguitarpro]

I built years ago a clone of la3a using a Monacor 100v speaker transformer.
It has't the .31 tap so I can wire it using 5w, 2.5 and 1.25 tap only.
Now I like to change them for something "better": I find that it react not very well to low freq material.
Is there somewhere a winding info for B11184 T4 transformer?

Thanks for help

I bought some replica replacements from David Kulka, Studio Electronics some years ago. They work very well.
