Question about Amplifiers & Preamps
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.
