If it will be stable to about 24 volts,than i am happy. ;D I almost never need voltages higher than this,so it is not important to me. I am using this partlist: Do i need to change something,since my transformer output voltage is to low?Or is this partlist ok for stable 0-24V and about 2-3 amperes? Thanks for the zener suggestion,i will change it if i can find some around here. :D Thank you very much for your answers. 8)
