Ok, so with the help of all you people specially GlassWolf, I took the courage to open the amp and here it is. Laugh all you want, 8A 50W transistors each channel, 2SD718 complementary to 2SB688... Hmmm, what if I changed them into some more powerfull, eh? Lol!
Yeah, you're right as usually, but I was joking about it, to change them I'de have to replace also its drivers (the small ones), and possibly calibrate the all system, which is a work I'm not fit to, either by lack of knoledgement or equipment... What I really have to do is find a way to check the speakers impedance, or if the transistors isolators are leaking... You know, witch hunting! Cheers!
