Hi Pal,

We would recommend contacting support@marshallheadphones.com or contacting your dealer and they will be able to advise on repair or replacement.

Marshall Support

I was reading an article about Stockwell vs Kilburn and I noticed that Marshall has very attentive support team. I doubted it, because communications via email doesn't fit that recommendation, but as you bring your product for the repairing, you know that you have one of the best team at your back. That's my personal experience and I hope it will help to somebody, someday.
