this project is characterized by a high circulating current
especially in the differential input stage
in fact is a current mirror CFP
the next stage is characterized by a bootstrap titpico schema Jeff Rowland
Then the typical triplet EF emitter follower
if you like to use the simulator calculates the optimized values of 35V dual
Thanks😀

I don't see the point of the two PNP transistors in the collectors of the input diff stage.
The b-e junction is shorted so there will never be collector current...
Why are they there?

I looked at the Ultimate Supplifier, and it's not correct what You have drawn.
If You have any idea behind that transistor is, I guess more than me is curious on what it is.

The C-B of the two transistors are coupled in blocked mode.
There will not flow any current from the collector up to the B-E-joint.
Again, what ais the purpose of the two PNP-transistors on the diff input stages collectors?

normally in the input stage using transistors with low Ic on the natural bias voltage 0.6 V
this method allows to obtain a driving current of the stadium in tension much wider because the BJT PNP has deliberately characteristics of current@0.6V higher

Crossover
I would like to do the speakers for amplifier 60W RMS / 8 ohm. I watched the speakers Woofer Beyma 8BR40/N - 50W RMS, 35 - 6000 Hz, 90 dB, 8 ohm and Tweeter Beyma T2030 - 15W RMS, 1,5 - 20KHz, 95 dB, 8 ohm with crossover Beyma V2 hifi, 300 W, freq 3 KHz, 8ohm.
I turn to you, because I'm not so sure that this is a good relationship and frequency of cutting 3 KHz correct
Would it be better if I would use stronger tweeter and would cut the freq to 4 or 5 KHz
.
Does anybody can help me with advice and calculation for crossover
Best regards

Probably because I registered for the first time today and I'm still a beginner. Please help me.
Go to the forums list, Look up the group "Speakers"
There You will find "Multi-Way" as the forum where it would suit fine to post your question.

Now I see what it was supposed to be.
Base connection is in the wrong place in post #1 schematic.
OK, thanks for clarifying your intent.
