You can check out this link:

There is another website that describes it better, but I can't find it anymore.

You can also check out the second picture in this thread for the minimalist implementation.

The mains bulb tester is dynamite!
Just get a socket from your home hardware store for the price of a couple of fuses!
So easy to build, saves you so much trouble.....

Reusing my own thread with another question.

The amp is now more or less finish..

On the left channel (speaker terminals on the back) the DC offset is 70 on the right channel it's 4...

Anny suggestions how to fix It.,, (most probable cause and so on)

Can the amp be used with such large gap in offset?

Hi,
that 70mV is just about tolerable for a medium duty 8ohm speaker.
But it indicates something very different between the two channels.
Investigate and try to reduce below 20mV

Sometimes with all else equal, the diffirence could be down to a chip itself... Play around with your earthing configuration too...

That 70mv should be quite audiable, so it may be worth looking at fixing...
