Eu am 116V,dar dupa schema mea ar trebui sa fie 107V.Insa toate celelalte tensiuni din sec chopper sunt OK si din semireglabil B+ se regleaza in plaja 110-120V.Cred ca e o greseala de tipar in schema mea.

( daca se incadreaza corect siglele programelor ). Link to comment Share on other sites More sharing options...

bassbox Posted October 22, 2009 Author Share Posted October 22, 2009 Aveti dreptate in leg cu TDA 9830.Dar in momentul de fata este cam off topic.Am umblat numai la partea de alimentare.Incercand sa verific tens de alimentare si mi s-a parut ca ceva nu este in ordine.Cu B+ 116V rastrul e normal, dimensiunile sunt OK, iar celelalte tens din sec chopper sunt OK.Incercand sa scad B+ la 107 V,(valoarea pt B+ din schema) nici nu este posibil fara modificarea unor rezistente si celelalte tensiuni scad prea mult. Diagonala tubului este de 48cm. Link to comment Share on other sites More sharing options...
