DIY audio Amplifier in Class A

[santosa]

Hello,

I search a best schematic DIY audio Amplifier in Class A with recent transistor.
The power 15 to 30 Watt/8 ohm.

Sincerely.

Coming to mind:
- the JLH one
- the Douglas Self one in class A version
- the Stan Curtis, but those transistors might be harder to find.

Hi Santosa,
the Analog Devices Application Note AN-211 describes "The Alexander Current-Feedback Audio Power Amplifier". A very intresting schematic with output-DC-controll circuitry.
You can find it by going on the SSM2019 Product Page, then click on Application Notes on the right.
