Hi guys!
Want to show you my first about redy TDA2009 chip amp. It's only need to finish its case.
It sounds good, hasn't any hum or extraneous noise.

LM3886 board (100x100mm) and adapter for SURE DSP.
LM3886 circuit board is made in such a way that up to 4 pieces can be put on top of each other. Fuse, rectifier, transformer and relay control need only once.
At the top, you can also mount the board with the SURE DSP, the 5Volt power supply is also provided by the power supply of the amplifier.
So you can quickly and easily build a stereo power amplifier, or a 2+1 or 2 way fully active.

How good are Samxon capacitors compared to Japanese and European made - I think they are Chinese...
In India, Keltron is pretty good, it has the tech from Sprague, Belgium.
Sprague of course is an American company famous for its quality.
