I have an old Marantz Amplifier ST353 has suddenly developed a problem where the output side of the unit is effectively non existent. I can have the whole unit connected as per normal but in order to get any sound out of it at all, I have to have the volume cranked to maximum and even then, I can only just hear it with head right next to speaker. Could this be power supply problem to amp fets or something more sinister? Rest of unit functions as per normal. Any help would be greatly appreciated as when working, is a ripper little unit.
