Well according to all of the posts in this thread and I have read every single one, The answer is NO do not use the original schematic! Use the newer one posted in this forums thread. Glen

Ya I get my SMT parts from Newark and Mouser, they would have them too. I''d have to wait for a while until i need lots of parts before placing an order, they charge $15-20 for shipping. Not sure what Digikey charges for shipping. I am using the APO445 op-amps for the old project. If and when I make the new project I'll use the MC34071 or TLE2141 But for now I'm playing with the old board, to make it work better. If I'm not happy with the results, then I'll make a new board using the correct new schematic and parts list. But for now I'm playing with the the old version and experimenting. :) Glen :)

Had a look for MC34071 and TLE2141 op-amps at the supplier and on EBay but could not find them! Did find and bought 3 OPA445 op-amps on EBay. Glen

I'll asume you are responding to me :) Yes thats why I'm upgrading the rest of the components on the original board as suggested by you in the second post on page one of this thread. New resistors, transistors, larger cap, extra power transistor .33 Ohm 2watt resistor....... This parts list here! http://www.electronics-lab.com/forum/index.php?action=dlattach;topic=19066.0;attach=16238;image Glen

Ok so I can use the MC34071 or the TLE2141 as drop in replacements for the original schematic and board I built? to replace an TL081? I'll go look at the datasheets for those two op-amps. I checked my stock of op-amps, all I have is low noise ones for making stomp boxs 18 volt max :-\

Well I have decided to just mod the existing circuit board, using audioguru's part list, from post #2 I'll try that first, if it still isn't adaquite for 24 volts 2 amps, then I'll make a new board for Redwire's parts list. Only part I could not locate at the supplier were the OPA445 op-amps. So I'll see what I have in stock that is comparable. I'm enjoying reading the posts!!! Glen :)

Hello everyone! I built this power supply two days ago from the original site, and found this link today. I have just spent about two hours reading every post in this thread. LOL too funny! Seriously that web page should be corrected or pulled down. Anyway very entertaining. @Audioguru Do you not get tired of answering the same questions over and over again in the same thread? I don't understand why people don't just read the thread instead of asking questions that have been answered multiple times. Glen :)
