Please need help to calculate gain from circuit.

FriedMule:
Can anyone help calculating this amplifier circuit's gain?
I do not know if this task are a insane large one or even manageable. For me it is totally impossible.
You have properly seen this circuit before, that Is what I constantly are bothering you with! :-)

DuPe:
roughly ×5?
(100k//100k) / (10k+2k).
anything right of level shifter are emitter followers, having gain of about 1
FriedMule:
not more then 5?! wow that was not much!!

Does that mean that a i.e. CD-player with a line out at 1Vpp only end in 5Vpp to the speaker?!

It is more than that!

The 10k resistor is bypassed by the 100uF // 100nF caps!
So the gain is (100k//100k) / 2k = 25

FriedMule:
Thanks a lot, so it is about 25Vpp out pr channel?
Does that not sound as about 36W out?

EDIT: the transformer are 26V-0V-0V-26V on the schematic, it is about 80W out, why?
