    Yes, this is close enough. I've worked on these before, but it's been a few years.

    Thank you so much

Marshall Mg30DFX guitar amp volume level cuts in and out! Anyone know how to fix this or what the problem is?

I have just fixed one of the amplifiers with this fault. It was a poor solder joint on the headphone socket. The ground of the speaker is switched through the headphone socket, so if there isn't a good connection, the speaker volume drops, but the headphone output is still OK.

Is the input jack for the guitar the same value as the one for the footswitch on a marshall mg30dfx? thanks!

No it is not, they provide different functions and the impedance values are different. Hope that helps..

I need the schematics for a Marshall MG-10KK guitar amplifier in order to repair it! I'm a good technician but I don't speak english very well... rsrs Thanks!

Most of the problems with the small guitar amps are blown power amp chips. They usually use chips like the TDA2030 which look like a power transistor.
Most other problems involve broken connectors, bad solder joints or cracked circuit boards. The power supply area is so simple one doesn't need a schematic for that part which is usually just three terminal regulators for +/-15 volts. Schematics are often hard to find.
Try this site, although this is a different model, much of the schematic will likely be the same.

I have bought a second hand guitar amplifier, and would like to know, how to do a safety check on it, using a voltmeter or whatever, hank

First and foremost make absolutely sure you know what you are doing. If the amp is in good working order you should be O.K. The biggest safety check you can do is make sure that no one has removed the ground prong from the power cord. If it doesn't have one then you should take the amp to your nearest qualified amp repairman who can do a certified repair on your amp. For instance if it is a Marshall product, take it to a Marshall dealer. This type of repairman not only has the training, tools and schematics to work on your amp he will also be able to tell if someone has done a safe mod to your amp. Not only that he can be held contractually responsible if you are injured through the correct use of the amp after he has done the repair. Read your service agreement carefully before allowing the work. Amplifiers can kill you.

What is the fuse rating for a Marshall MG30dfx?

According to the schematic, the fuse for 120 volt is a 1 amp.

This is a reasonable size for this size amp.

My Marshal MG30DFX has started to boom with excessive sustain even in a clean state with controls at minimum when using my Epiphone les paul...any ideas what's wrong

Sometimes the sound can feedback onto the strings of the guitar effectively sustaining.

Also check it with reverb off. Sometimes the effects loop and create sustain.
