Same design alpha-nirvana-39w-8ohm-class-a-amp. https://www.diyaudio.com/community/threads/alpha-nirvana-39w-8ohm-class-a-amp.344540/
Clarification:
We are not talking about the identical or even similar design, but only about the idea of regulating the quiescent current and at the same time pulling the current source along with the signal ... to put it quite simply.
What we need now is a really hot logo for any kind of incarnation of a Beelzebub and not a reference to Nirvana.
The Beelzebub is much more attractive and charming than its competitor AlphaNirvana39 - simply better and more diabolical, black.
😉
logo wanted!

I would use a 2*18vac /min 100VA toroidal transformer ---> +/-24 to 25Vdc.
This means we can guarantee 40Vpp, which is good for 25Wrms into 8Ohms.
There are many degrees of freedom - and this is here the case.
Choose the better one to improve.

The better one is still' what an individual builder prefer..!
"100uF and GND" is fine, a very good option.
We need a Logo 🙂

Why is that?
Beelzebub's work is guaranteed to be deadly 😉. I believe it and I know it too, for sure - nothing is pre-cooked, but hot.

bring your amplifier to life before ("die Abrissbirne" comes - my next project offer /idea)
This one is not better than alpha-nirvana-39w-8ohm-class-a-amp., even lower than .
first .. , should review again https://www.diyaudio.com/community/threads/alpha-nirvana-39w-8ohm-class-a-amp.344540/

Would you please justify this statement? Why should the design of this thread be ranked lower than that of the competitor thread? The Beelzebub is certainly better than the 39, and above all much nastier. However, I don't play ping-pong in this respect.
Build, measure & compare in a double-blind test (BB25, AN39, Douglas Self's Blameless B - as DUT for example).
over and out,

Everyone can realize their very own Beelzebub, improvements of any kind can be made according to their own taste, so that their own Beelzebub is the world's best 25W class A audio amplifier.
My initial idea can be found in this thread as well as lineup's 1st recommendation.
Adason has agreed to do a comparison with his Nirvanas, which of course is only possible if Adason gets himself a Beelzebub (which he has to bring to life himself) ..!
That's all I'm going to get into on this subject 😉.
Better or worse is always in the eye of the beholder - the function is there, what more do we want(?).

Here is a very first sketch, still to be simplified further.
Let me know if you feel it should be even nastier or rather friendly!
