Thank you audioguru for the info and please don't think I question your answer because I know next to nothing about electronics. Here's the rub, I just put a small voltage bench supply together, two 14v outlets, one plus, one neg, using center tapped trans. I was curious as to whether this one could be modified so as to have more output v and amps than the first one and have +/-. I have the parts for this 30v supply on order and thought maybe with some changes I could do what I asked about. Probably to late for that now?

One more question. Is there a way I can get +/- outputs on this supply. I am going to build it anyway but would be even more handy for me if I had both. Thanks.

Thank you much, I will go from here.

Hope I am posting right here. What I would like is the revised schematic of this power supply and also info on where to purchase pcb. I have the revised parts list posted by audioguru. Thanks

I am new here and new as a hobbyist. I noticed a 1-50v 2a bench supply that was listed by hamed-iranmehr that sounded interesting. However I would like +/- outputs. As I said I am new and have no particular need for this, I would just like to build it. I just finished a lower volt unit, 18v out, and would like to try a more difficult one. Any schematics for something like this? Thanks
