Sfat-Amplificator audio 50W

Recommended Posts

Schema are unele gre?eli ?i ptr tensiunea aia de alimentare nu merit? s? folose?ti triple?i pe ie?ire, ?i în configura?ie cvasicomplementar?. 50W are numai pe 4 Ohmi, altfel scoti 25W pe 8 Ohmi. Sus de tot g?se?ti multe scheme, mai bine alege de acolo una mai bine realizat?.Merge înlocuit cu un BD139, trz superdiod?.

Schema asta am mai f?cut-o acum câ?iva ani,e dintr-o revist? Electronistul ?i a func?ionat bine dar...v? cred c? poate avea ?i gre?eli. Din p?cate am apucat s? bobinez traful la 2*25Vcc ?i vreo 5-6 A...?i mi-a luat ceva timp...pot g?si o alt? schem? mai bun? tot la tensiunea asta? Dac? da, ce îmi recomanda?i?
