Question about Marshall Mg100dfx 100-Watt Combo Guitar Amplifier

Marshall MG100DFX noisy

I have a 2004 Marshall MG100DFX Combo. Sometimes when I turn it on it makes a very loud popping and scratching noise. It's been doing it rarely, but today it started doing it and now I can't get it to stop. Is it something simple, or should it be looked at by a professional? I am pretty good at fixing electronics, but this one has me puzzled. I would love to trade it in for a MG50DFX, because I really don't need 100 watts.

Before you bring this into a shop, try spraying out all of the controls. Use an electronics switch cleaner that contains a lubricant. Spray into the control and work the control back and forth a number of times to loosen up any dirt inside. Then spray it again.

Let me know if that resolves the problem.

Thanks,
Dan

My amp makes a loud foghorn type noise whenever turned on. Even if i have the volume turned all the way down and the guitar unplugged it still hums. I'm not sure if its an amp or speaker prolem. I took...


Likelly the TDA7293 chip in the power amp has failed. It shorts to one power rail and drags the power down where it hums... this CAN damage the speaker if left on. Verify the problem and replace the chip. Slight chance there are bad electrolytic filter caps but those are easily spotted.

When I use the over drive effect channel the head makes a rapid beeping sound.


Make sure your guitar cannot "hear" the amp as the guitar can be a pretty good microphone to cause feedback. Feedback sometimes saturates an amp and causes "squeging" which is a cycling into and out of feedback.

Could I gut this Amp and MAke it Tube?


Maybe. The cost involved wouldn't reward you enough. Here are some links for you:http://www.drtube.com/marshall.htm and http://duncanamps.com/index.htm and http://www.ampix.org/ If you have all the tools, parts, schematics and above all experience. You may end up with something you like. Personally I would look for a vintage Marshall that needs a rebuild and start there. You will end up with a great amp and the experience you need to mod the MG100DFX if you really want to do it. Hope this helps.

One speaker of my MG100DFX makes loud noise similar to a guitar disconnect. When that speaker is disconnected, noise stops. What is the suspected problem?


NEVER disconnect a speaker with the power on the amplifier !!!!!! Good way to blow the amplifier.

If the speaker rattles while you are sending audio through it, it is likely damaged. It should be inspected as there are several failure modes, some of which as hazardous to your amplifier.

First test is to gently move the cone and listen for any rubbing of the voice coil. If you hear rubbing, then the speaker needs replacing OR re-coning.

Sometimes the magnet breaks off the back of the speaker.

Investigate this before further use.

Hi,I turned on my Marshall mg series 100 dfx and there is no sound,just static comes on.Its starts with a kinda bad feedback sound than turns to loud static.


I suspect the power supply for the effects processor has failed. The effects unit will "go crazy" when power supply is too low voltage.

If the amp has loud noise, then the power amp portion is PROBABLY OK.

I had a similar problem in a Behringer amp caused by a bad electrolytic filter cap.

More than likely you have a power issue. Look closely at the main filter caps. These are the 2 larger than the other caps. They are usually about 4700uf at 63v (generic values but yours should be close). Check them for swelling, if no signs of that then you will need to due a capacitance check on them. Sometimes but not always, they will show bad on an esr meter also.
