thenr.

I've bought mine on eBay, but it's 10000uf not 12000uf... good price, fast ship. http://www.ebay.com/itm/2PCS-AUDIO-Electrolytic-Capacitor-30-41mm-10000UF-63V-63V-10000UF-/251121225080?pt=LH_DefaultDomain_0&hash=item3a77fdcd78

OK Thank you audioguru... When the PS is finished I post the results here.

Thanks audioguru, I read the answers about to use two 2n3055. Will one BD139 be able to support both tranzistors ?

I'm making my power supply 0-30V inside an old ATX power supply, and I have 2 Fans. How should I select the side of the flow? Should I make throwing air at the heatsink or throwing the air which is inside the power supply out? Sorry about my poor english.

Hi Ajax007, forget the original version. You should see the xristost's schematic the following link: http://diyfan.blogspot.com.br/2012/02/adjustable-lab-power-supply.html

Hi, I wanna know your opinions about building a UV Box using black painted cardboard box. What you think about ?

Hi, i will use a power supply 24Vdc 3A instead of a Transformer. Can i eliminate the rectifier diodes, R2 e C2 ? I didn't find MC34071, only MC34072. Can i change ??
