"Alte Schule" - The five-minute amplifier approach!

However, I would like to refrain from recommending the variant in posting #55.
This thread is intended to show examples of what is possible and where possible adjustments could be hidden.

But I wish you lots of fun and all the best gannaji.

greetings,

Note

I (sitting in front of the screen and dumbfounded) have fallen prey to a flight of faith:

The THD graphs shown here should of course not simply be automatically equated with 20 = 20 W in x-axis. The power here is referred to a reference power of 1W in the pseudo unit dB, i.e. 10 times log10 of (power/1W).

Apologies for this faux pas, So "Alte Schule",does much, much more than just 36Wpeak into 8 ohms.
With far more than 30Wrms and with predicted THD values far below 10m% - this circuit is now very attractive.


Bye,
HBt.

Why should an audio amplifier design be more complex than it needs to be? Less is definitely more - and the path shown here points to almost unbelievable THD figures, so why not limit yourself to the simplest approach? It's economical and will certainly survive any party unscathed. I am convinced that the “Alte Schule” is a very good hi-fi audio amplifier and has absolutely nothing to hide.

I would be happy to produce a PCB, a layout - for the DIY forum and its enthusiastic members. “Alte Schule” puts every current dumper approach in its pocket.
