pune-l si tu printr-o rezistenta de 100k la masa sau la plus... trebe sa mearga in una din variante (acum nu am timp sa studiez schemele)

shi mai e inca o chestie, in kit pinu 9 e dus la + printr'o rezistentza de 2,2ohmi shi la minus printr'un condensator de 100uF. mi se pare ciudat, ca in datasheet, pinu 9 e direct la +

e o filtrare suplimentara a tensiunii pentru partea de preamplificare....la cat costa integratul, poti sa-l inlocuiesti pe cel din kit.. oricum e foarte "robust" sa zic asa, asa ca e posibil sa-l fi "exploatat" tu necorespunzator de a luat-o razna...

am si eu 2 bucati care s-au prajit amandoua odata si manifesta cam aceleasi simptome se incalzesc mult si nu se aude nimic . Parerea mea ca la cat costa nu merita sa iti pierzi timpu cu ele

Daca ave-ti kiturile cumparate de la adelaida verificati traseele. Am avut unul care facea la fel se incalzeal de-l luau dracii si muzica ioc, problema era urmatoarea pinul 8 imi dadea la masa din cauza unei ramasite de cupru ramasa pe margine. Si mai e ceva Izolati marginea cablajului daca vine in contact direct cu radiatorul.
