LM386 on steroids -buffed up amplifier!

This is the buffed up version of the LM386 amplifier circuit- the LM386 on steroids!

The R resistor sets the gain.It can be between 3,3R and 820R .But be careful. Too small a resistor can result in a lot of noise.I've used a 520 ohm resistor here.

Here is the schematic.Original schematic diagram was found here.

Here is the actual pcb.




Both sides of the pcb

The pcb in the real world.

The unpopulated pcb.

Last but not least-the pcb layout in actual size.Print it as is.

If you don't know how to make the pcb  take a look at this.
