Small class a amplifier project

[Antivot]

I would like some pcb layouts for a small class a amp ...3-5 watts ...and if it`s posibile a eagle or target file ... so i can print it and start building ...

Here you will find something looking good, but no layout nor PCB. It is so simple you can do it fast.

The test circuit used by Rod Elliott is a very basic Class A with resistor loaded output ( 8 Ohm ).
This schematic shows +24 Volt supply.
But it will actually work without problems at lower voltage, too.
And you could very well use other transistors with good results.

yeah, but as neither of the circuits at the end of the page are proven it might not be good for a first go


the author states:

"Here is an untried version with component values"

"This circuit could also possibly work as a low power class-A amplifier"

Anyhow another simple option might be something that doesn't even require a pcb - just use point-to-point wiring.
