Question about Marantz Audio Players & Recorders
Hello I am a technician of chili am repairing an amplifier marantz model pm 750dc who presents audio distorcionado in left channel, I change the transistors of exit, the transistors driver, the condensers electrolytic and the constant fault I need help
The input selector switches if they are dirty can make the amplifier sound like it has a blown channel.
compare voltages from the left and right channel and make sure they are identical as well as the power supply,typically + and - 65vdc .check the regulators for the pream,they run panel lights off the same circuit + - 14vdc
