That's my fear. It's why I came here and asked you. I found a lot of projects using LM317 but I didn't find a good one. Don't you know anyone?

Hi guys... I was thinking better, so I won't do this project right now. Do you know a good project for a small power supply? Like 0~24v 1A with current protection or something like that? Thank you

OK. I already have the 2N3055 so I'll use them. My idea is use the little transformer just for a while. When I can afford, I'll buy a good transformer and the 12.000 uF capacitor. Thanks for everything.

Thanks audiogoru and Enforcer83. I already know the ripple problem with a smaller capacitor and a big current. But,what I meant to say, is that I don't need more than 1 A. So, can I use this project (audiogoru's 3A version) with my little transformer (24VAC / 435 mA) and a smaller capacitor, like 3300 uF? What more I need to change in the project?

Audiogurus, I'm doing the improved one. I did the original and now I have all the components waiting for something. This is why I want to do the good one. Actually my idea is use a transformer with 2A or around it. So, will it work? Another question: Can I use a smaller capacitor than that ones with 6.800 uF? They're very expensive and if I use a smaller transformer I think they'll be unnecessary. Thanks again.

Thanks audioguru. So, I can use any transformer on the project, but it will work at a limited power? All I need to do is change R7 and everything is gonna be OK? What more do I need to change?

Hello guys. Firstly I have to say how you've helped me with this project. I've built the original project and it was such a fail... So, I have a doubt: If I use a 24VAC/435 mA transformer on the audioguru's project (3A), it will work? It's all I have here :( Brazil regards!
