doru tv gsm Posted April 27, 2022 Share Posted April 27, 2022 Salut,am acest amplificator audio cu o problema ciudata,la pornire canalul dreapta intra in protectie aproximativ 10-15 min si pe urma decupleaza protectia,iar in timp ce functioneaza cu semna are intreruperi pe iesire.cine a intalnit acest defect?

VALENTIN STANCU Posted April 27, 2022 Share Posted April 27, 2022 Salut.Verifica condensatorii de filtraj, cei de 22000uF la 63vcc.Sigur sunt umflati si uscati.Bafta. Quote Link to comment Share on other sites More sharing options...
doru tv gsm Posted April 27, 2022 Author Share Posted April 27, 2022 Da,sunt un pic umflati dar simetria tensiunilor pare ok! Quote Link to comment Share on other sites More sharing options...
modoran Posted April 27, 2022 Share Posted April 27, 2022 Pai si ce astepti sa-i schimbi ? Sigur ai riplu cat cuprinde ce nu se vede pe multimetru. Vezi sa nu ai si lipituri cu probleme - refa toate lipiturile, in special in zona etajului final Quote Link to comment Share on other sites More sharing options...
