Zgomot de fond la un amplificator

Recommended Posts

Satlutare am si e o problema si am nevoie de cateva sfaturii.

Am facut un amplificator si are un zgomot de fond care e enervant.

Zgomotul vine din conexiunea dintr-e amplificater si corector de ton. Am folosit cablu ecranat de calitate dar totusi ramane zgomotul de fond dar am observat ca modificand pozitia cablului zgomotul se atenuieaza sau accentuieaza

Poate ca problema e ca am pus potentiometrul de volum la intarea corectorului?
