Question about Audio Players & Recorders

1 Answer

Marantz Amp I have a Marantz 6010OSE KI signature amplifier that has a problem. Whenever the amplifier is moved, the left channel stops working, or will only emit very weak sound with no bass. If I tap the side or top of the case eventually it will start working again. Sometimes it will start working again straight away, and at other times it will take quite a few taps before its right. Any ideas?

    No, it is still just out of the right channel when I turn it up

    Thanks for the help Graeme, I had the top and back off the amp last night and checked everything. There was nothing obvious regarding the soldering, but when I put it all back together, there was no sound out of either channel, until I pressed the source direct button, then perfect sound on both channels. Does this suggest it might be something to do with the balance control (there are no tone controls)?

    Many thanks

    Thanks Graeme, I will give that a go and hopefully all will be ok.

    Ah, could have been a speaker protection relay, but this fault often clears when you turn up the volume.

    Sounds like dry solder joints in the amp. Have you removed the covers and checked about the power stages for dry solder joint, or cracked heat stressed connections about output stages and power supply. 90% of problems in audio output stages are generated by fry joints and soldering failure. I often blanket resolder every joint, to ensure that there are never any again in the future.

    Gte back to me here and we can go further after you have checked for soldering problems.

Hi, well done in diagnosing your problem:) From what you have just told me, the amp has noisy source selector switching, and may even have more than one switch or control causing the problem. Start with the source/direct button.
To resolve this, best bet is to "flood" the internals of the switch or control with CRC 2-26 . This will clean the contacts and leave a layer of lubricant to prevent the problem reoccurring, Getting the spray into the controls is the hard part. Check out what you find by way of entry points that you can get a the delivery straw into to spray. Sometimes you can use the a hole on the top of the switch, or "click" the top of it a little, enough to get the sray in. If the switch is a hermitcally sealed type, i have in the past used a pin vice and a very small drill to make a hole at the very back of the switch creating a place to get the spray in. Check it out and see how you go.

Can i connet my marantz ki17 amp to a power amp

Hi, i don't really understand why you want to connect an amplifier to an amplifer.
Might be that you want to get a louder volume or ?don't know.

I don't think there is any need for you too connect marantz ki17 amp to a power am. Both do the same work, but might have different watts.
So you will need to check what you want to connect with the amplifier first and check the watts that can carry it without interference from the amplifier.

I guess that would do the magic.

Have a nice day.

Hi, I have a Marantz PM7200 KI Signature, This morning sadly realised that the amp is gone, There is no light on, something like no power. Firstly, I look for the fuse socket but there is no socket on...

First of all check the power at the socket to which you have connected the amp.If you are not aware of electronics, then do not go for a test with an amp like KI signature.
it will have a fuse in its inside. its only blow off if there is some fault inside the its circuitry. consult someone who is well equipped for the same.

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?

Amplifier blown channel

Chances are it's something on the heatsink that's gone. The internal fuse would cause a dead amp. If it's still working it won't be the fuse, unless it has fuses all over the place!

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.

I have a luxman m-117 the left channel stops working

Hiya, the first thing that comes to mind for me is the bias setting is incorrect. This is a common mod done by many people that often leads to bad things! The good thing is that it does sound likely as everything is OK at this point (hopefully).

I suggest it goes in to be checked and get someone who knows amps to set the bias correctly. I would advise you try (unless you have a bit of experience with meters etc) as things can go bang.
The bias setting for the amp are 0.5mv between TP1/TP2 and same on other channel TP3/tP4

Hope that helps

Marantz Pm-7200 left channel weak compared to the right

hmmm. Let's start by swapping the wires you are using for your speakers. Double check the wire connections first, then take the left and place iton the right and vice versa.
