Recommended Posts

din link-ul tau am gasit Q1-2=BC550C [matched]Q3-4=BC560C [matched]cum pot sa imperechez BC550/560 ptr ca nu stiu(sigur) daca imi va da imperecheati la firmele de specialitate; inca ceva: face referire la text, iar textul e in graca, tu cum ai facut bobina L1 si ce era legat de led?

tranzistoarele BC trebuie sa aiba aprox acelasi B(beta), Hfe sau cum i-o mai zice

cumperi multe bucati (e cam 1000lei vechi bucata) si masori cu aparatu d masura(acolo unde se masoara tz) si pui in circuit tz cu aprox aceleasi valori

 

detalii d bobina pe site

 

bafta

am reproiectat circuitul ca nu imi placea cum e acolo si am pus GND-ul direct pe cupru ca sa nu am probleme. Te rog sa te uiti peste schema si sa imi zici daca sunt destul de groase circuitele
