Nelson Pass has a website namned 'First Watt'. That is for good reasons.
Because the need of a power amplifier is often just 1 Watt.
This is the feature of this my amplifier.
It delivers 1 Watt and not much more.
The need is a power supply of 12V.
The adjustment is to set an idle current of 37mA in the output stage.
The transistors are MJE3055T and MJE2955T.
They were chosen because they are TO-220.
The actually max output is like 1.17 Watt.
You will be surprised how much sound you get from just one Watt.
It is a really fun project.
And it will teach a lesson.

Of course it can be scaled up.
But this is not my idea.
The same concept could be put on a supply for example at 30V.
This would give close to 10 Watt output.
Would be another topic, not like here about be satisfied with 1 Watt.

I keep a scope on my system set to a 1 watt window (+/-4V) just to amaze people with how loud a 1 watt amplifier can be...
