I am fairly new to the guitar scene, and I bought a Marshall DSL401 tube amp a few months ago used. It's been having some weird issues this past week. After playing for about 10-15 minutes, it starts to have this weird crackling noise, and it's pretty loud. I suspect it's a problem with the tubes, but I'm really not sure. Any ideas? Appreciate the help in advance

That's the crossover year. Some time in 2003 they upgraded the rectifier bridge because they were overheating. You may have one of the faulty ones. Have a look at the board under the bridge, if it's scorched then you will need to replace the rectifier bridge with a bigger one, preferably one with a heatsink.

It's not a particularly hard job. You may have to ream out the holes in the board a little for the bigger bridge but it's not hard to do.

yup...it won't be as difficult as you think, just pay more attention and be careful, that's all you need...once you did that..next time you will be much familiar with it..
