    I got all the resistors and small capacitors in and ready to solder and then I remembered what one U-Tuber said "test test and retest at any point that will provide useful results it is much easier to test early than to troubleshoot once it is built" so I pulled all the components out and tested them so now I can restart my build.

    I bought 3 pre-order kits. They now cost less. I was thinking of using them to feed small projects to replace batteries. I think it can be fed with voltages below 24 Vac. I did a little test. Without load: Vac = 19,6 Volt --- Vcc out = 21,2 Volt With load (8 ohm and Vcc = 8 Volt then 1 A) Vac = 18,86 Volt --- Vcc (without load) = 8,04 Volt --- Vcc (with load) = 7,98 Volt. Note: The maximum current before the protection is: 8.72Volt / 8ohm = 1.09 Amper. I also tried with a lower power supply. Without load: Vac = 16,4 Volt --- Vcc out = 17,1 Volt With load (8 ohm and Vcc = 4 Volt then 0.5 A) --- Vcc (without load) = 4,02 Volt Vcc (with load) = 3,99 Volt. Considerations: I could not measure the ripple with my toy oscilloscope. The output voltage setting is rough. A multigiro or 2 in series potentiometer is preferable for a more accurate adjustment.

    mounted all parts on pcb, tested on 24ac input.. posible to control V and I with potentiometer but the output voltage is max 6,5V ?? some problem with transistors or IC. will be easy to repair if producer attached el. drawing for pcb. lm317 get hot on o,5A load, need good bigest Radiator

    tudo certo e bem embalado, pena que os serviço de entrega do Brasil é um lixo

    just want to build one without ac transformer and able to have current limitation. DC in DC out, for noise free radio tuning etc.

    Stavebnice lineárního regulovatelného zdroej 0-30V 0-1A. Perfektně vyrobena deska plošných spojů. Otvory pro osazení součástek jsou prokoveny a upraveny pro snadné pájení. Koupil jsem dva kusy - vše OK. Uvítal bych dodání schéma pro snadnější hledání závady.

    Arrived in good conditions. Assembled (to easy actually) and testing whith old transformer 14.4 v single. Looks like work properly. Waiting to arrive new double transformer 12-0-12v AC 30w. Order new kitt to make one home made power bench supply.

    Habe mit diesen Bausätzen mein neues Universal - Netzteil bestückt Makel: trotz genug Versorgungsspannung aus beiden Netzteilen nur 17,9 Volt
