Buongiorno, mi chiamo Giorgio e sono in attesa dall'Italia (Savona). Sono un appassionato dilettante. Ho un lettore CD MARANTZ 17 con il seguente problema: con il volume impostato al massimo sul telecomando l'uscita RCA è "bassa" su entrambi i canali
Checked the muting "signal" when the CD Is playing and It Is -11.5 volt. I read that 2sc2878 transistors used as Muting, could easily get destroyed/damage under certain conditions. It Is possibile that despite the signal NO MUTE (-11.5 V) the transistors (2sc2878) perhaps damage conduct a part of the sound to ground and therefore the output Is low ? Where could the fault be ? I don't have and oscilloscope. Sorry for my bad English. Thanks in advance tò anyone Who wants to help me. I am attach the cicuit diagram of the muting marantz CD 17. Hi Giorgio

Good morning, my name is Giorgio and I am waiting from Italy (Savona). I am an amateur enthusiast. I have a MARANTZ 17 CD player with the following problem: with the volume set to maximum on the remote control the RCA output is "low" on both channels
