Ziua buna,am reusit sa termin partial montajul modulelor finale MX800.Partial deoarece mai am de procurat finalii recomandati.

Asadar am montat un set de tranzistori finali 2SC5200/2SD1943.

O sa va prezint doua filmulete in care o sa vedeti in functiune doar modulul final alimentat la o tensiune de +/-33V,apoi impreuna cu modulul de intrare si alimentare la o tensiune de +/-90V.Biasul a fost reglat astfel incat pe rezistorii de putere sa am 5-6mv 

Amplificatorul functioneaza foarte bine,se aude clar,curat,este mut fara zgomot de fond.

Felicitari Donpetru si pentru acest proiect reusit!

Mersi @niksound pentru postare.

Si eu am inceput asamblarea modulelor dar astept de mai bine de 3 luni sa soseasca de pe aliexpress niste capacitoare de filtraj. Initial am dat comanda de niste capacitoare, nu au venit, am pierdut 2 luni, am cerut "refund" si acum e in curs alta comanda. Sper sa vina de data asta!
