I never thought an assembly manual for such a simple circuit was needed.

You can find schematics for amp and power supply sections here: http://www.audiosector.com/lm4780.shtml

If you click on Application Notes link, it will get you to pics and short info I posted on a Forum.

Simple for you Peter, not simple for others, however he may just be wanting instructions so he can build it 100% perfect so he has no troubles.

Just a thought.

I don't see how to make better instructions than what already has been posted: http://www.diyaudio.com/forums/showt...565#post636565

When I released both amp boards, I posted detailed instructions here on a forum, in this thread. To make it easier find it later, I made links from the pages describing each kit; just click on 'Application Notes" shortcut.

The PS for LM4780 kit is basically the same as for LM3875, and you can see it here (LM3875 PS): http://www.diyaudio.com/forums/showt...429#post584429

Please note that in LM4780 PS diodes are reversed though, and black stripes always indicate metal tabs.

Yeah well.. new pics later. Seems like I have the caps on the wrong boards.. guess the higher end components have different values than the schematics ... DOH.
