Hi I have a Marshall reverb 12 model (5205) its a 12 watt solid state practice amp. Whilst playing through it and allowing a chord or note to naturally fade away the sound becomes broken up and fuzzy, on the odd occasion the amp has also cut out briefly this happens with either clean or distorted amp settings. Can somebody advise me on what component/s to change, I am familliar with electronic components and soldering but my fault diagnosis is very limited thanks CFB.

Huh, it can be many things - from cold solder joint to the faulty component like PS cap. Troubleshooting can be made with some (sinusoidal) input signal, and tracing the fault through the amp, from output to the input. Tech?
