Reparatie si testare T-Amp T1050 model nou.

Recommended Posts

A venit cu un canal in protectie, s-a scos tot ce tine de finali si prefinali pe ambele canale, s-au inlocuit cu MJL21193 si MJL21194 respectiv MJF15030 si MJF15031, s-a recalibrat bias, si direct la teste:

 

Clasa AB, alimentata la +/- 90Vcc in gol, practic este T-amp T-2400 fara partea de Step Up Switching, cu alimentare mai mare pe partea de AB fata de T-2400.

Am avut amplificatorul asta cu finali 2SA1943,2SC5200 din fabrica.Era impecabil,n-am avut nici o problema cu el...l-am vandut ptr.ca-l foloseam rar de tot.L-am folosit pe niste boxe t-box...2x15'' +1,75'' driver,boxe pe 4 ohmi.Chiar daca-i china si nu-i ceva super scula de firma isi merita toti banii,parerea mea.

Este clona dupa QSC.

 

Daca foloseau componente adecvate, si respectau anumite chestii precum originalul, era si mai OK, oricum este supravoltat cu vre-o 15V pe rail.

 

Cu MJL-urile, daca nu cedeaza op-ampul de la intrare (99% din cazuri ele crapa cind crapa acel NE5532), ar trebui sa nu mai aiba probleme.
