First, thanks a lot of the reply.
I have been salvaging speakers amplifiers for a lot since i like listening to hardbass during my lab time.
Now back on the power suply, i know the circuit isn't the best, but it's like everything my strating point, some time in the future i will buy a proper power suply but now i can't afford it and my mum(i'm 15) won't let me buy one anyway. Still i need one to test lasers and stuff, so i need a very basic one now. Still i'm following an old magazine that here in italy was very famous and now fallied so now all his versions are free too download.
Getting back to the circuit, i have the capacitor with the high esr(mesured it with the diodegonewild esr capacitor tester from his website) and it works(according to my meter) . . . Soo i only miss the cc feature, no op amps for now because i don't have any on hands, i can't savage any from anywhere and can't buy any. Hope you can still help! It would be pretty great!
