Step 1: Deco.
A plastic base from a broken audio system can be the top. I placed the critical parts for the best view above.
Step 2: Handmade.
Everything you need are welding skills and patience.I also add equalizer with three pots in the middle front.
Step 3: Extra Features.
Inside the shell of broken audio system made the volume meter with some led lights , all power for extras get it from a dvd player supply pcb. 5v,12v.
The power tranformer for the lamps are outside, 220v - 220v. 250 watt.
I worked with it almost 4 monthes to finish it , to get the best of it you need knowledge from someone old technician who workes with amps in the past.
