Introduction

Issues with the sound quality of the speaker can be resolved using this guide. Since screws can get loosened and mess up the sound quality, the speaker can be tightened or replaced by following this guide. It is very important to remember to unplug the device before attempting to replace the main speaker.

    • Remove the back cover by using the vent hole as a grip.

    • Gently pull out the back cover and let it hang on the side of the speaker that has the knobs and power switch.

    • Unplug the main power lead from the control board; this allows the back to be opened more, allowing easy access to the power switch.

Google search doesn’t give many results for replacement speakers. Where did you get your replacement speaker? Thanks.

I am looking for the replacement Speaker as well

Sean G -

The device page has a couple of references that could help you find purchasing information on The Marshall Kilburn.

I’m also looking for the replacement speaker. Jeff Feuss, you mentioned the “device page,” but I’m not sure where this is (I just joined this site). I get the point of “ifixit,” but I’m ready to call in some help on the repair at this point. I’m going on a year of trying to get my speaker back in working condition. I’ve tried the third party location where I purchased it, BestBuy (wouldn’t service it), and a local electronics repair company. Marshall has been absolutely no help; they only service the Kilburn (1st gen) at the center in England. However, they require the originating address to be in England (won’t return the speaker outside of England). I’m currently seeking friends that live in England. :-)

andrew graham -

I guess throw it away and spend another 350.00 because nobody can find a 25.00 dollar speaker.
