MR3 MOS mister elucidat

Recommended Posts

Se pare ca din cele din urma sa elucidat misterul tranzistorului remarcat din amplificatoarele produse de RM. Ca urmare defectarii tranzistorului original performatele acestuia le-am egalat cu 2 tranzistoare recuperate dintr-un monitor, respectiv dintr-un UPC. Primul este un 2SK752 iar al doilea un IRFZ24N. Nu am studiat datele de catalog insa merg la fel de bine ca si cel original. Singurele modificari aduse amplificatorului este schimbarea condensatoarelor din circuitul de intrare si cel de iesire. C6,C7,C8,C10 si C11. Folosind tranzistoarele de mai sus grupul C6-C7 totalizeaza 420p, C8 370p iar grupul C10 si C11 570p. 150+150+270. Probabil mai sunt si alte mosfet-uri care merg in locul celui original. Incercati si voi iar rezultatlele scrieti-le aici.Bafta
