Question about Marantz MM9000 5-Channel Amplifier
My m9000 has stopped working. I can hear the solenoids click when I power it up but there is no output. Also, the power and standby lamps fail to come on. I replaced the internal fuses as new. There is no sign of burning or any burning smell whatsoever. Any ideas?
The main power transformer may not have the correct voltages coming out of it. I would check the output volts at the terminals. I would also check the out puts from the solenoids.

MM9000 where the reley clicks in is most likely due to bad solder on input RCA board and output terminal board. Easy to fix.

Sometimes you wont smell anything funky.
If the outputs are powered by big module ICs , chances are that one or both have failed.
First things to check are all the speakers being properly connect ( AT BOTH ENDS)
How would you know if the transformer voltages are ok unless you had a service manual?
