amplificator Omnitronic P1500 2x750w defect

Recommended Posts

salut.... pe scurt am un amplificator Omnitronic P1500 care in prima faza functioneaza corect ... cupleaza releele insa se aude foarte incet asa cam ca la casti ...am inlocuit preamplificatoarele dar nu sa schimbat nimic .... ...proprietarul spune ca la folosit cateva ore la maxim la un aveniment dupa care sa oprit iar acum se aude foarte incet in boxe ... astept cateva informatii de la cei care ati mai intalnit asa ceva ..multumesc

Vezi ca la trompetele astea chinezesti trafurile de retea sunt bobinate cu sarma de aluminiu....verifica tensiunile de alimentare,bafta.

Puterile de la omnitronic sunt made in Germany nu sunt trompete chinezesti.
