it's worth to build it ?
No...Both gain stages are not optimised for high gain at low distortion....
Even worse, the output stage employs a simple current limit...Which limits output current when it isn't necessarily required, and doesn't when it is needed....Bad!
Yes,
I would not operate a BJT amp (unless dedicated to a known load) without at least 2slope SOA VI limiter. that could be fixed with 1 more resistor,2 diodes and a couple of small c's for lagging.
Mikeks could do it in his head I'm sure?
rest of the cct is pretty ordinary but functional.

Hi darkfenriz,
The 6K8//100n is to equalise dissipation in the diff'l pair, as the other one is cascoded and not seeing full rail voltage. Matching the dissipation helps minimise DC drift.
