Guest ekid Posted January 29, 2008 Share Posted January 29, 2008 am primit sub nas un amplificator AAS 101... si am schimbat integratele TDA 2030 care au intrat in deriva termica.... apoi am mai cumparat un set de integrate care au avut aceeasi soarta... de unde sa fie problema? daca ma puteti ajuta cu vreo schema sau vreun sfat in ceea ce prieveste depistarea si remedierea defectului.... multumesc....

Guest ekid Posted January 29, 2008 Share Posted January 29, 2008 dupa o inspectie relativ sumara condensatorul C14 e umflat desi are tensiune de lucru de 100V avand capacitatea de 470 microfarazi. e posibil sa se fi defectat si altceva? sau sa fi afectat si integratele?

zal Posted January 30, 2008 Share Posted January 30, 2008 Daca nu ai schema, cauta pe net un pdf cu TDA2030 si schimba toti cond electrolitici, mai putin cei din sursa, rez alea românesti verzi ca li se desprind picioarele de corp si cond ceramici de valori mari, zeci-sute de nF.

Everest Posted January 30, 2008 Share Posted January 30, 2008 Trebuie sa fi atent ce TDA-uri cumperi ..... majoritatea pieselor noi nu prea corespund datelor din catalog. Eu as merge pe varianta "din recuperari". Ce tensiune ai pe alimentarea lor ??? Quote Link to comment Share on other sites More sharing options...
