As i said...
I give up.
But, anyway, i would like to try it
i'm still lost with this questions:
May i use some "standard" configuration for TL072 and duplicate it in every amp?
I'm already have a 12v power supply, what's te best to put in the end in order to light for example, a little car bulb? or better, a bunch of leds?
Please, i'm very interested in how to make this project, i learned electronics, but was 20 years ago.
I learned a little about op amps then, but i barely remember.
This is my first project since then, so, every help will be grateful.
Luix
