Think of yourself in 1983 for the amplifier STK080 served distortion for Ro = 4 ohms and were 0.0006%!🙄

You are right,
(Virtual stones, of course) 😉
specially when they post the same nonsense time and time again, impervious to the shower of stones.

Re:
In schemes amplifiers are sometimes different errors, and updates, enter the person designing, sometimes there is no other way to patch and schematics are repeated.
For people in other types of amplifiers not possible to produce.

Hello!
Favorite Top hi fi amplifier P6W/4R.
Power transistor beta-lin. 0.25A/0.5A = 0.7% max.
People do not understand: this circuit amplifier as low as the god himself is nothing if it is not exactly perform (1983/STK080 Ro = 4R-THD = 0.0006%).

Can not help that almost everyone is crazy.
There are those who do to divert people attention from the good things and generally write just stupidity and there are those that the electronics do not know, I just read what anyone writes.

These circuits remind me of the second amplifier I built. I was 12 years old. It worked, and it sounded pretty bad. There was no bass, very poor dynamic response, very poor in general. But I took it out a couple of months ago and hooked it up and it still worked. I scavenged it for what few good parts it had (real 2N3055s silly I know) and used a few of the parts in a DoZ prototype. That sounded sweet.
Speaking of 2N3055, are any of the modern ones any good? I heard that some of them are nowhere near spec and some even have two dies in parallel in an attempt to meet power spec. Are the rat shack ones OK? They're expensive. I would like to buile a few DoZs for various applications (like headphone amp and tweeter amp in a triamp) and the 2N3055 works well in the output stage. I want to keep it simple and be able to reliably apply the "dominant pole" compensation scheme.

And you don't understand it.
These are 40 year old industry standard circuits. I've seen them a million times. There are reasons they are not used anymore.
Perhaps you could design a modern circuit that employs the best features of these legacy circuits?
The one that measures the transistors and makes amplifiers schematics knows what he's doing and finally knows what affects the quality of the amplifier.
You can download STK086 hybrid transistors, a gain of b = 135 and are good for the amplifier P6W4R.

You're supposed to tell us "what affects the quality of the amplifier." If you can't, you should be asking questions, not posting nonsensical jibberish. Most of us here know way more than you do. You don't even know enough to not understand what you're talking about. I hope you don't think that you sound smart. You almost come off as a bot.
If you want to see what's wrong with your beloved classic designs, and want to see elegantly simple and effective remedies of these shortcomings look here. Distortion In Power Amplifiers
I've used some of these solutions before in my own designs, but Mr. Self has come up with a design that addresses all the shortcomings in one design.

can we have this guy banned? perhaps it doesnt break any official rules though, he uses dogged, blind stupidity to baffle and enrage.
its a complete waste of space/bandwidth, surely nobody could really think this is hifi, or even mid-fi.
ive seen this posted as headphone amp, poweramp, low poweramp all in this childlike illegible text and pictures, I cannot call them schematics.
perhaps he has some stocks of all this old crap and cant get rid of it?
