Secretly I've wanted to build my own lab power supply for a while. However, I am at a loss for how you did it. I'd be grateful for step by step instructions! By Noah Sachs, at 4:56 AM Very nice. Would you be willing to create a one-off AC-to-AC wall transformer, or do you know any person or company who might? By Mucka Mucka Man, at 10:53 AM Maybe I will come out with PDF version of instruction later. For the time being, I redraw the strip board layout to make it easy. I hope this may help. By LeorickSimon, at 11:55 PM How much voltage/current can this circuit cupply? I've been dying to make one that will cleanly supply 12v@10A. By alanv73, at 6:39 AM I'm using 500VA transformer. Theoretically, on 50V max current is about 10A. Since both 2N3055 can support up to 30A (15A each), the limit depend on the transformer it self. If you have larger transformer maybe u can increase this value. But you need a bigger heat sink. I never try to test the current limit before (afraid of burning it).
