Servo stabilizer Will a Servo stabilizer would help use my Marantz PM 6004. It trips-off often due to poor power supply in my home and in my area where i live. Amp works fine in the morning as the power supply is good at this time. However, in the late evening it starts tripping due to poor power supply.Please help.

SOURCE: Marantz PM 4000 has cut out

May be the problem solved here :

Dear Sushant,    I do not think your use of an equalizer has caused any problems.  I will explain the proper use of the source/direct button.  This button's function is to monitor the output of a recorder connected to the record outputs of your amp.  When this button is pressed on the sound going to the speakers comes direct from the "source" (cd, radio tuner, phonograph etc.) when in the off position you can monitor the recording of whatever source is being recorded via the tape deck.  This switch must be off to record through the amps record outputs.    To test this, put a blank tape in the tape deck, choose the source as phono and place the dec in record/pause.  With the source direct button pressed on you should hear a change in volume when moving the amp's volume knob only.  When source direct is off you will be able to hear the output of the tape deck, so adjusting the tape deck's record level will also affect the volume coming out of the speakers.  more record level in/ more level out.!    Below is copied from page 9 of your user operation manual for Marantz's explanation of the source/direct button. 
best of wishes, Michael Mittelsdorf

SOURCE: trips on power up

It has a short circuit on the final steps of the outputs, maybe the common called "final transistors or power amplification IC (integrated Circuits)"are blown. You don't have the ability to resolve this problem, so take the unit to a facility authorized repair.

In stereo terms your system is "clipping" which means you are pulling more amps than the system can handle. If it happens only when you use the mixer, I'm thinking the mixer cant handle the power. Check the specs, It should show maximum amp input.

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.
