I like the color

I will buy a compressor shortly. So I can build beautiful speakers, meubelairs, and more importantly.... amplifier boxes and panels!!

hi

In the page web he/she says that they are obtained 2w but I obtain 3w about to clip wave.

I have painted the panel with cotton, alcohol and red ink. And not with a compressor. :-)

The amps is post in this website:

Hello!
This is the obtained graph using the Bass-boost switch it is not very lineal (a little more and it is good for RIAA).
It has very good sound although alone 2W.
Don't pay attention to the THD of the graph. If a stylized source this percentage is used it is smaller
