Bogner 20th xtc a/ab mod

[dorrus]

Hello guys.
I have a Bogner 20th xtc without the A class option.
Is there a schematic about this A/AB switch and does anyone know what hardware I need to make this mod myself, or is it a hard job
and should I better leave this to classified people?

Isn't this the 2nd time you've asked for schematics here??

I already have got an answer to this question from setneck on another forum, so thanks Andy!
@Ventura : No, i never asked for a Bogner schematic in this forum
