Question about Marantz Audio Players & Recorders
Used to go to alternate between working and low level of sound with lots of buzzing but now got getting anything.
It sounds like the output transistors went bad What I would do is check all output transistors in the unit they are usually the large transsistors on heat sink that an ohm meter and check each transistor while unit is off and no power go base to collector then emmiter to base if you get o or continuity on those legs on any one they are bad .

Look at the final out transistors. I'm not sure if you would have transistors or an amplifier pack? It has 8 to 14 pins maybe. Look to see if there are any burnt components,cracks, or where something got hot. Most components break down because of heat.Also look for bad solder joints.
