Could be a power supply failure or a Power "On" switch failure.

SOURCE: the fuse keeps blowing in my marantz pm-57

Goo day sir, the T on the fuse has nothing to do on you marantz fuse blowing up, chances are you amplifier is shorted, check you IC amplifier/power transistor for shorts. Check also your speaker impedance. usually they are 8 ohms. You can use a technician's multitester device to check the impeadance. An imbalance or mismatch speaker can cause a fuse to blow and destroy your amplifier. hope this helps.

I have a MARANTZ PM 151 Integrated Amplifier thats about 20 years old. I have not used it for a few years now and when I tried it recently it will only play from one speaker. It worked fine before I put it...


Hello
Long time storage may have make electronic contacts to get poor and fungus infected. Your set need a whole service. During service they will clean all the contacts and rectify repairs if any. Get it serviced. OK.

Marantz dedicated amplifier squeals


The symptom sounds like a feeback loop. As long as that indicator is showing near maximum output on one channel AVOID ATTACHING ANY SPEAKERS TO IT!!!! You'll cook the tweeters.


Turn it off and manually operate every control, knob and pushbutton throughout its range many times to wipe oxides away from their conductors.

Set all EQ controls to their midpoints and re-evaluate.

We don't know if it's an input or output problem yet. Does it do that with all inputs?

Marantz PM-74D


OOPS-forgot to mention if your bias turns out ok after replacing any blown outputs, turn it off and resolder the collectors (center) pins of all 4 output transistors and turn it back on-should work but you'll need to recheck bias and dc offset. They appear to both be adjustable on the board sticking up on the top side-it's right in the middle and has 4 trim pots on it......
