Devreyi yaptım çalışıyor. 12.05 volt gibi bir değer aldım.
This is a pretty strait-forward circuit. You might need to
bypass C5 with a bigger capacitor (10-100uF). Diode D makes up for the BE loss
of 0.7V of the 2N3055 transistor. If you need higher voltage, use 7815 instead
of 7812 and connect pin 3 directly to ground. This will give you 14-14.3V on
the output. I built several power supplies like that for my CB/ham stations and
they work very well. Of course you have to add mains transformer and rectifier
bridge + smoothing caps, just like above. Caps should be as big as possible
(20000uF or more).
