SOURCE: marshall mg 100hdfx fan

Some of the Marshall equipment uses computer size fans and even on occasion the same connection.

Take the bad fan with you to a computer repair shop it will be much cheaper than a marshall part they should be able to help you out

Testimonial: "that sounds like the best way to do it..will just take fan to computer shop and try and get a replacement...thanks for the assistance"

Try to remove the fan and look for the sticker on the back side where the wires come out.

Remove the sticker, underneath it there will be a small aluminium cap (sometimes there is no cap and the axis is readily visible when you remove the sticker).

Take the cap off with a sharp tool (it shouldn't require a lot of force to do it), now you should be able to see the fan axis being held in place by a small clamp - put a drop or two of machine oil in there, move the fan blades a little to make the oil flow past the axis into the bearing.

Reinstall the cap, put the sticker back in place, reinstall the fan and test it.

Sometimes this will make things better, but if it doesn't then it is only fair to replace the fan.

SOURCE: I need the schematics for a Marshall MG-10KK

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.

SOURCE: My Marshall MG 50 DFX has a noisy fan. Can I take

Bo, the fans cannot be lubricated. If the noise is from bearings, replacement is the only option.
