Vlad.Florin Posted December 7, 2022 Share Posted December 7, 2022 (edited) Incerc restaurarea unui amplificator Yamaha A1 care din pacate are probleme cu ICurile 2sk100 si care sunt imposibil de gasit Oare in locul lor se poate adapta NSVJ5908DSG5 ? Poate mai sunt user cu probleme cu aceste ICuri si informatia poate le e utila si lor Multumesc https://www.onsemi.com/pdf/datasheet/nsvj5908dsg5-d.pdf Edited December 7, 2022 by Vlad.Florin Quote Link to comment Share on other sites More sharing options...

sonic11 Posted December 8, 2022 Share Posted December 8, 2022 Se poate inlocui cu componente discrete doi tr. jfet inperecheati si cuplati termic. https://audiokarma.org/forums/index.php?threads/yamaha-b-3-rebuild.943998/ Quote Link to comment Share on other sites More sharing options...
Vlad.Florin Posted December 8, 2022 Author Share Posted December 8, 2022 Problema e ca pentru inperechere e nevoie sa cumperi o mana buna si sa le imperechezi Plus ca mai e si calitatea indoielnica a pieselor actuale pe cand acestea le gaseam in stoc la mouser si aveam si caracteristici oarecum asemanatoare Ma mai gandeam si la varianta JFE2140 dar acestea nu le gasesc pe stoc https://www.ti.com/lit/ds/symlink/jfe2140.pdf?HQS=dis-mous-null-mousermode-dsf-pf-null-wwe&ts=1670482849460&ref_url=https%3A%2F%2Fro.mouser.com%2F Quote Link to comment Share on other sites More sharing options...
adydep Posted December 8, 2022 Share Posted December 8, 2022 (edited) Caută 2 bucăți BF245,le lipești între ele capsulele cu super-glue și vezi ce zice.Părerea mea că este că o să funcționeze. Edited December 8, 2022 by adydep Quote Link to comment Share on other sites More sharing options...

Vlad.Florin Posted December 10, 2022 Author Share Posted December 10, 2022 Problema cu 2sk389BL e ca nu se gaseste sa il comand chiar daca potriveste de la distribuitori gen mouser digikey farnell SOS Singurul loc unde l-am gasit dar nu am comandat niciodata de la ei ar fi digipart unde este 58 de dolari iar pretul mi se pare putin cam mare fata de ce am propus eu mai sus mai ales ca eu am nevoie de 2 bucati....
