    Convert 0-30V 3A PSU to 5A or more

    Yes it will work mate because I didn't find a 3300uF Capacitor and used a 4700uF instead. and also the Diodes I used are 6A ( to be safe ) and it works

    0-30 Vdc Stabilized Power Supply

    Hehe thanks buddy for the compliments :D and sorry for the 50w resistor :p because I don't have one. Here is another picture of it so even the people who are going to build it will have an idea of the layout :) (sorry for the dirt on the table but I was just drilling a PCB lol)

    0-30 Vdc Stabilized Power Supply

    Ok People I fixed it :D So take this as a tip: IF IT varies the voltage from 23v to 35v ONLY, you got the Emitter and Collector of the 2N3055 Mixed UP lol.. Cheers!! when I arrive home I will post some pictures if the administrator lets me (until I arrive home I hope the administrator will...

    0-30 Vdc Stabilized Power Supply

    Hello All I have built this power supply but I got a problem. As soon as I switch it on, the volt meter reads 23.5v and then I try to vary the Volt Pot, it goes up to 35v! In other words, my PSU is only variing from 23.5v to 35v !! I have changed the op amps twice and even tried the TL071 (which...
