    I put it off for a long time, but I finally decided to build a regulated power supply. I bought more if I wanted to build more. Now I still have to find free time to build. The packaging was not perfect, one potentiometer has bent leads, but otherwise it is fine. Operational amplifiers are not labeled, maybe they are clones.

    Not tested yet, but i have got these PSUs before, and i think they are good. You just have to do the research and the small upgrades. Make shure you have some form of back current protection (if you charge batterys for instance... ) And DO NOT run it too hard or the transistor will burn out.... It is no problem to take out 5-6 amps if you have the cooling (some proper cooling ribs combined with a laptop cooling fan with temperature control do wonders), but do the homework and the upgrages first!!

    Good quality pcb. Components quality not up to the standard of the pcb (electrolytic capacitors, transistors and some resistors). However, given the price, is a good bang for the buck product.
