Cool Pics of my new amp

I finally finished my first chip amp.
It uses 1 TDA 7293 per channel. Transformer is 2x23V 300VA. There are 6x4700uF caps in supply, and another 4x1000uF near each chip.


The sound is

How did that happen? Were there flames involved, or just a lot of smoke? Very nice looking amp, though. Did you put the printing on the front pannel yourself, or did you buy it that way? If you did it yourself, I'd like to know how. Just out of curiosity, what are the toggle switches and LED's on the left side of the amp for?

accidentaly I shorted -Vs and GND while testing, and the chip exploded (a lot of light smoke and noise). Big badaboom.

I did it myself. I used some thing called letraset. Those are little letters on a piece of transparent paper. You can buy them in bookstores. The only thing you have to do is place that transparent sheet ove some surface and write over letter which you want, and it will stick to the surface. It is very simple process.

The first switch is for powering the preamp. Little green led indicates when it is on.
Second switch is for mute/play. There is a little light in the main power switch of the amp which goes off when you turn the amp on. Then the red LED below second switch goes on indicating that amp is on. Green LED goes on when you put the amp in play mode.
The third switch is for selecting sound path (direct from chinch or over the preamp).
