    0-30V Stabilized Power Supply

    Hey guys, first off my son spilled something on my laptop and my keyboard hates me now so I apologize if my grammar/puncuation/spelling is crap, I will do my best. I have just about finished the PCB, I used two thin single PCB's and made a dspcb, and since I am using a dremel to do everything...

    0-30V Stabilized Power Supply

    Ok. I just ordered everything off newark (xcept xfr) for just over 20$. Actually, I got 3 of almost everything just in case. I ordered 3 power transistors in case I build the 5amp. I decided not to be cheap and bought some Aavid heatsinks with a thermal resistance of 4 degrees/w. Ok that was a...

    Thank you Audioguru. I am going to build the 5amp that... Redwire? built... I am going to try to use the exact parts he used to try and avoid the endless troubleshooting. Another bonus is that since we are both using microwave transformers I might luck out and have a near identical power source...

The only thing you need is a 9v supply (which...

What are the key points to consider for the op-amp if I decide to use a different one? I have several lm's and others laying around, as well as a bunch of tl081's I bought to make...

    0-30V Stabilized Power Supply

    Ok, I have been following this and waiting for a transformer to build this since last year, and the other day I finally ran across a microwave and decided to try my hand at rewinding it (thanx to... Audioguru? Whoever it was that did this for the idea). Well, after a couple of failed attempts...
