EmyRulz Posted October 27, 2008 Share Posted October 27, 2008 "minusul" de la difuzor leaga-l direct la masa sursei de alimentare. Link to comment
Dr.L Posted October 27, 2008 Share Posted October 27, 2008 hmm,sursa nu ar trebui sa fie stabilizata,doar o punte redresoare si condesatorii aferenti(ma rog,si sigurante+rezistente de descarcare pt conzi)banuiesc a e vorba de un amplif de putere,nu de altceva Link to comment
avyrez Posted October 28, 2008 Author Share Posted October 28, 2008 asta e sursa stabilizata Link to comment
cipcirip Posted October 28, 2008 Share Posted October 28, 2008 Foloseste redresare si filtrare, simplu, cu o punte si 2 condensatori, diodele de pe placa aia par prea mici, si in plus nu ai nevoie de stabilizare pt alimentarea etajului final.p.s. ceva gen :http://www.elforum.info/download/file.php?id=20305 Link to comment
avyrez Posted October 28, 2008 Author Share Posted October 28, 2008 pot sa o fac si cu 2 cond nu cu 4? Link to comment

ratza Posted December 19, 2008 Share Posted December 19, 2008 Prima variant? e cea corect?. Dac? pui rezisten?ele în serie, limitezi curentul foarte mult. Link to comment
Dr.L Posted December 19, 2008 Share Posted December 19, 2008 a doua nu va functiona,deoparede pe rezistentele alea va cadea mai toata tensiunea destinata amplificatorului Link to comment
MifTy Posted December 21, 2008 Share Posted December 21, 2008 ... dar dac? nu pune deloc rezisten?e??? Link to comment
hip_hop7575 Posted December 30, 2008 Share Posted December 30, 2008 rezistentele le pune pentru a crea o masa falsa (cred ca asa se numeste),pentru ca are alimentare simetrica la placa.Rezistentele alea trebuie sa fie intre 10k si 22k. Link to comment
