  • Marshall DSL 100 P-Board problem.

    I ain't sure what a P-Board is, but my Marshall amp haven't made a sound in months. I took it to my local music shop and they were unable to fix it. They gave me the product they needed to fix my amp, but they can't find it and neither can I. Any help of suggestions?

    The product number is: 1499674 P-Board JCM 2000

    The main board with the tube sockets on it is what causes all the problems with those. If its the one that was OEM'd, it will be a pale green color. You need the replacement which is a darker green and made from better material. The main issue is the crappy phenolic-ish material they used on the original board became slightly conductive over time and causes output section meltdowns. The new board will fix it. You'll need to have a factory authorized service center take care of the repair. I don't think they'll just sell you the board. And besides, the bias will need to be set once the board is replaced. Just let someone else worry about it....

    I'm scratching my head over what kind of "tech" can't repair this amp. Really......whats up with that?

      Ain't sure either, apparently where I live there ain't a lot of good technicians. I myself want to go study abroad for this so I can return with knowledge. I also live
      kinda far from any good music shops, so I am still stuck with a dead amp. I messaged Marshall's main site to ask what to do and how to return it, but nothing yet. Is there a way to find any factory authorized service center? (I live in the Caribbean btw, no specific island)
