johnny_tl: fi te rog mai explicit, cand deschizi un topic nou... scrie in titlu ideea de baza a problemei tale!Titlul dat de tine "Ajutati-ma va rog...pls" suna a ajutor umanitar, mai ales ca-i la diverse. Spor la lucru!

Uite aici am desenat o schema de oscilator - generator de ton. Pe aceasta o foloseam cu succes acum vreo 4-5 ani ca generator ton intr-un transceiver (generam codul morse).

Alimentarea este la 6V. Schema este constructie proprie.

Constructie proprie? Nu zic "NU", dar schema aceasta o stiu de vreo 10 ani si inca am in biblioteca cartea ce se numeste "Un tranzistor, doua tranzistoare" editura Albatros - anul 1978

Pot pune si o poza la rezolutie mai mare daca nu se intelege.
