Schema postata are cel putin o greseala: scurtcircuit B-E la T4 - 2n3055.

 

PS: cred ca sint mai multe pt ca nu are feedback de la iesire ci de la intrare ?!? Tensiunea ce se intoarce de la iesire este limitata/stabilizata la 2.7-3.3V de un zener.

Ramane de decis unde trebuie intrerupt scurtcircuitul B-E... Eu propun ca mai jos.... ca sa existe si o protectie rudimentara la scurt pe iesire...in rest nimic spectaculos, un etaj diferential , referinta alimentata din tensiunea regulata, care apare abia dupa ce apesi Start si creste incetisor prin R7... inovatie Made in RO ...cu ceva inspiratie de la rasarit.

...Sper ca n am gresit ceva in desen?...
