I bought my amp in 2017 I think it was the first series, it was totally new thing on the market. It went wrong about a mounth ago. I brought it to a dedicated engineer, who knew what could be the problem, He told that it is a common mistake with these amps (I don't know the exact english name of it) , where the elctricity arrives to the amp was too sensitive. Marshall changed it later. There is no part for the original, the new part is not good for the old amp, so there is no way to repair it. Is it true?
I assume you are saying the power supply is no longer functional? If that's the issue I wouldnt say that it was a "common mistake with these amps".
If it is a faulty power supply I would suggest that an engineer who know what he was doing could possibly repair it. If it's a fault with the digital side of the amp then I doubt anyone could repair it.
