Shambala Posted April 26, 2022 Share Posted April 26, 2022 Tensiunea de alimentare maxima a lui TDA 2030 este de +/-18V (sau +36V si - la masa). Quote Link to comment Share on other sites More sharing options...

bmwh548 Posted April 26, 2022 Share Posted April 26, 2022 Integratul cu care s-a facut inlocuirea e recuperat din aparate vechi sau e din productie noua? Quote Link to comment Share on other sites More sharing options...

bmwh548 Posted April 26, 2022 Share Posted April 26, 2022 Din ce am citit cele noi sunt niste mizerii. Mai ales ca acolo e ceva in neregula pe alimentare nu cred ca sunt sanse sa "cante" prea mult un integrat nou. Pe iesire s-au folosit condensatoare de calitate? Snap in? Cele cu terminale normale nu rezista prea mult si pot genera si ele confuzii in depanare. Quote Link to comment Share on other sites More sharing options...
