Giorgian tv Posted October 25, 2016 Share Posted October 25, 2016 Va salut colegi si buna dimineata,m-am apucat sa construesc un amplificator audio de pe o schema germana si m-am inpotmonit la acest tranzistor pe care nu il am si nici nu am lucrat cu el niciodata,teoretic stiu cam ce ar trebui dar practic nu,rog pe cei care a mai inlocuit acest tranzistor sa-mi spuna si mie cu ce la inlocuit,nu de alta dar nu vreau sa iasa artifici din montaj tinand cont de faptul ca se alimenteaza la 60v,va multumesc anticipat.

Giorgian tv Posted October 25, 2016 Author Share Posted October 25, 2016 Totusi mi se pare cam mic,eu m-am gandit la un BD237. Quote Link to comment Share on other sites More sharing options...
adydep Posted October 25, 2016 Share Posted October 25, 2016 Nu-i mic,BC141 are 1A ?i 60V,iar BD 139 are tot 1A dar 80V.Da,BD237 are 2A la 80V,e mai tare ca originalul. Quote Link to comment Share on other sites More sharing options...

Giorgian tv Posted October 25, 2016 Author Share Posted October 25, 2016 Cauta BF257,258 sau 259 facute de IPRS. Ce sa caute aceste tranzistoare intrun amplif audio?,acestia sunt buni ca finali video in tv-uri. Ce sa caute aceste tranzistoare intrun amplif audio?,acestia sunt buni ca finali video in tv-uri. Sigur teai gandit la ideea ca au capsulele identica,nu-i asa? Quote Link to comment Share on other sites More sharing options...
zsjkuki Posted October 25, 2016 Share Posted October 25, 2016 Sincer nu am citit postarea pentru ce anume are nevoie am zis doar ceva ce ar merge pe capsula TO39.Poti pune linistit si 2N2219A chiar daca asta e de comutatie. Quote Link to comment Share on other sites More sharing options...

Nu,nu merge,mai ales ca acest tranzistor nu este pentru aplicati audio,citeste despre el si ai sa te convingi. Quote Link to comment Share on other sites More sharing options...
