Cool! Many thanks. What a nice forum - and nice people here ;D And I thought I'll be executed because of not reading EVERYTHING of the 69 pages thread. Which emitter resistors can you advise? 0,1R/2W Resistors each? Thank you very much audioguru!

Hello! I just build the cool power supply and it works great. Many thanks for this nice project! 8) I can regulate the current with a hot-wired Output from 0,01A to 4,6A. Works great. But how can I protect the output transistor when there is a short at the output. I fear I will demolish the 3055 when making a short with maximum current. Using some 3055 parallel? I don't want to use a heatsink which's bigger than my workbench ;) Any ideas about a protection circuit or so? Maybe a relais which turns off the voltage when the LED is on or so? Many Thanks! Roelli.
