    Hi thecross

    Marshall Valvestates have problems with dry solder joints making them do many things from howl, to distort, to not work at all. Your amp has probably fallen to this problem also. If you can solder, i suggest removing and resoldering the main pcb. This will sort out 90% of its problems.

Guitar amp continuous humming from speaker


Firstly, do not disconnect the speakers from the amp when it is on. Damage is possible.

You have a bad ground somewhere in the hookup. The first suspect would be your guitar-to-amp cord shielding connections at each plug, then, the wiring in your guitar. Try changing each of these to another as a trial, one at a time.

I have a lot of stastic when using the Volume knod, as well as when I insert my guitar into the INPUT jack on my Marshall MGP 9004 guitar preamp. I wish to replace them both. Where can I get the PROPER...


Before you change parts, get some De-oxit ( radio shack sells it)

Spray some into the Jack( plug into/out of a few times after) and open the amp and shoot some into the small open spots on the controls and rotate the controls a couple dozen times.

Try a different guitar and cord. If still problem, give the amp a bump without guitar plugged in. If amp makes noise, there is an intermittent internal connection,

Hi thecross

I have fixed so many of these amps over the years... Marshall Valvestate series of amps are notorious for dry solder joints developing on the main PCB. If you have the skills(or an old mate that does)Remove the PCB from the chassis and resolder any suspect dry joints and you will fix the problem. Check particularly about any components there the PB has changed colour. This is an indication of heat in that area, and heating and cooling is a major cause dry joints.
I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

There could be a short in the rectifier diodes or in the transformer itself. Can you take some measurements inside the unit?
