Ok, So I am looking around for a simple amp project as a fun build.
And I came across this page https://sound-au.com/project12.htm
And it got me thinking.
The last version on that page could be nice I think. Easy to stabilize and enough loop gain for decent THD specs.
Why is this simple input arrangement not used more often?
I always see the LTP in VFB amps or the basics of a diamond buffer as used on CFB amps.
But why not a single transistor?
The only downside is that it can't be DC coupled.
Using more modern output transistors could make this amp more then fast enough also.
Just some thinking.
Any ideas to improve it further are welcome.
Also any other simple amp projects are welcome.

The Amp Camp Amp in the diyAudio Store, has a single transistor input stage. In fact it has a total of four transistors in each amplifier channel. I consider it simple.
I've built a few of these and they are inexpensive and sound fabulous. Well worth looking at. https://diyaudiostore.com/products/aca-mini-bundle
