Nešto o G8000

Fantastican receiver u svakom pogledu, dobio sam ga u ne bas reprezentativnom stanju (vise na slijedecoj stranici), ali nakon velikog broja utucenih radnih sati, vratio sam mu mladost!

Inace G-8000 je vrlo slican vecem bratu G-9000 (koji se smatra jednim od najboljih stereo receivera napravljenim ikada), jedino im je razlika u slijedecem:

 

 

 

 

 

 

 

 

 

 

 

Dakle da sumiramo, osim ovih gore nabrojanih stvari (Tuner, phono, glavni kondenzatori i izlazni tranzistori) sve je ostalo istovjetno… A sada malo o tehnickim podacima….
