Hello,

I would present you my little T-amp based on a MKll TA2024 board. This is perfect to recycle old speaker for example. 

If you don't know anything about the class T don't waste one more second of your life and => google : T-amp ( i'm joking )
If you want the synthese this class is the best : Sound quality / price / volume compromise, that we have now.

Wiring diagram ( So simple that even really beginners can do it ) :

This wiring diagram is in french so this is the translation :

Alim = power supply
vue dessus = top view
Led rouge = red DEL
HP= speaker
Bornier HP = Speaker connector
Boitier= case

In my case, I chose only recycled materials. A square tubular steel and plywood.
But this step is optional because it's my case and i think you want your case with your design.

My piece of steel is 74*74mm and 150mm deep. My plywood is 15mm.


the first step is to cut the steel and polish it..

The second one is to made wooden facades.

The last step is to solder all according to the wiring diagram and assemble your box around the components.
 

Put you music, and be proud of your first little amp which has cost you less than 20 dollars :)

and again sorry for my english !
