Question about Amplifiers & Preamps

1 Answer

I need to replace the external fuse on a marantz Model 32 amp.

On the back of the chassis is calls for a 4 amp 250 volt fuse but also says to replace with the exact kind. I have found 2 types of 4 amp 250 volt fuses- a fast acting and a slow burning fuse. Which is correct?

Well, take good look at the Fuse itself on metal area.
If it says AGC, then fast acting.
If it says MDL, then Slow Acting.

If you cannot figure it out, then just use Fast Acting since it is more commonly used in smaller Receivers and Amplifiers and Fast Acting will cutoff faster (compair to Slow Acting) if there is any unknown Prblem with Chassis.

How to adjust input voltage for marantz 4060 quad amp?


The only way would be a voltage selection switch on the back of the unit, or changing pigtail leads on the primary side of the power transformer.

No power going into my marantz 44se amp.


Check AC main fuse inside the amp located next to the power transformer, if the fuse is open, just put another and if it blows let the amp as is, because if you put more fuses and blow them you just add more damage to the amp, let me know your results.

Hi mas_66,
Make sure that the fuse is the same rating with the old one.
If still symptom persist, I've suspected that your output IC is shorted.
You may hang this IC, then power up the unit.
Observe what will happen, if this cure the symptom then this is a clear indication that this IC is shorted and made the fuse blown while it is in the circuit board.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Marantz pm 7200 lost sound, only works when volume is up high, still looks like there are no high or medium frequencies.


You have either lost the pre-amp stage or the Main Amp stage. Since you have a problem on both channels it most be a part that is common to both channels. Something like an IC I would suspect.

Can't find replacement bulbs


Unit probably uses fuse type lamps, either 8 or 12 volt filament. Remove one of the lamps and look for voltage rating on end cap. You can order these lamps from Allied Electronics or MCM Electronics online

Amp blows fuses Checked out OK: output transistors, power supply.


The fuses are there to protect the internals of the AMP.....
Please check that the correct fuses are installed......
if the incorrect ones are installed then a fire may develope...

There should be a manufacturers lable on the external chassis that details the fuses to use....

Fuses now days can be slow blow or fast blow....so the correct fuses must be used.....dont increase the fuse rating past the chassis panel label...but make sure they are correct...if they are correct then the amp needs a service to determine where the peak loadings to the power supply are originating from...

Some one may have installed incorrect fuses in the past...
