Ive been struggling with this too, first the amp starts with irregular noise, then makes a high noise sound and stop working, I tell the store to replace and they denied, they says they are not responsible for this issue and says I have to ask for warranty with marshall but I cant contact you in any way. This is very sad I saved money for a long time to buy this because I believed marshall was a good brand, and as I see you are not taking any action to solve this. Please help me.
Hi Gerardo,
Thank you for you comments, if the amplifier is under a year old you will need to contact your dealer and they will be able to arrange to have this looked at for you.

Marshall Support
