Thanks! There it is. I could not remember of the existance of the build guide in the store.... Any risk in connecting wrong as in the picture?

Risk? None.

It’s not going to do much, however...

very low noise floor with that configuration - probably below room ambient?

This is fine.

However connect your speaker the other way around to restore absolute phase.

Finished the build in one long evening, had a blast! Abit finnicky the bias setting, maybe a 40 turn pot would be better?

I really love the sound, ready to sell my old amp

I wanna build a full size one, torn between f5 and aleph j .. any tips?
