Radiocasetofon Sanyo M2402

Recommended Posts

Guest

Va salut,Ma poate ajuta cineva cu schema acestui radiocasetofon Sanyo M2402 ?Sau macar tensiunea care o scoate transformatorul, din cauza unei supratensiuni acesta s-a ars, cu toate ca as paria ca e 2 x 4,5v ca / 300-400mA, dar vreau totusi sa fiu sigur.Pe traf am acest cod : 4-251T25177A, nu stiu daca e relevant dar poate ma poate ajuta cineva. Pe placa mai sunt 2 notatii MCL-43 HCS-4HB

Daca nu gasesti schema (este un model vechi ) vezi cu cate baterii se alimenta si pune un transformator care sa ii asigure tensiunea necesara.

Alimentarea pe bateri se face din 4 x 1.5v = 6v, deci ar trebui un traf cu iesire simetrica (cu mediana) de 2 x 3v.

Pui un traf de 6V si ai rezolvat problema(nici vorba de traf de 3V).Cum este redresarea cu doua diode sau cu 4?

Are o dioada dubla, notata pe primul rand cu 17 iar pe al doilea scrie 7C :jytuiyu . N-am mai intalnit pana acum aceasta dioda dubla.
