Yesterday I stayed up late and soldered the last components. Three o'clock this morning it was finished!
I must say it sounds great!

The blue tube preamplifier (aikido) is not used at the moment. I use my Squeezebox player with it's volume control directly to the amplifier!

The boards are designed for dual mono with power supply and amplifier-circuit at the same board. This requires two separate transformers which I didn't have.

Actually I use two transformers with single secondary, so I made a larger power supply for both channels instead!
I put some film caps on the board...

You people are right! The LM3886 is good

Hi Olle!

Ur amp seems nice.
How is the sound??

I want to build one too & intend to use Miguel Font's design (as you deed)

Did you modify the original schematic or values??(or any recommendations)

It sound's good! I have been playing music every day the last three months and I really like it!
I don't miss my harman/kardon at all

I used miguel:s design without modifications. It works's great, but I don't know if there are better layout's out there...

I'm not an engineer, I just like to build stuff designed by them
