Nedumerire conexiune la amplificator

Recommended Posts

Guest Rad3T

Buna. Sunt nou pe acest forum si incepator in materie de electronica, asa ca imi cer scuze daca nu folosesc intotdeauna o exprimare adecvata cand adresez intrebari sau raspunsuri.

Am primit de curand un amplificator de 50w pe care unele piese erau dezlipite sau lipite necorespunzator. In mare am reusit sa lipesc ce era in neregula insa, am intampinat o problema la un tranzistor. Nu stiu daca tranzistorul respectiv trebuie sa faca contact sau nu intr-un anumit punct.Am atasat cateva poze pentru a oferi o imagine clara

Intrebarea mea este: intre punctul A si punctul B trebuie sa fie contact ? (A reprezinta pinul din mijloc al tranzistorului)

Tranzistorul cu pricina este T2 (lipseste din prima poza), iar schema este facuta cum am crezut ca ar trebui sa fie, si anume fara contact intre A si B.

Multumesc de schema djlove. Acum inteleg cum trebuie sa fie conexiunile. Rezistentele lipsa R6, R61, R9 si R91 o sa le cumpar cat de curand si sper sa pun in functiune amplificatorul.
