TomN Posted January 5, 2007 Report Share Posted January 5, 2007 Do we talk amps here? I just joined and didn't see an Amp section, I know it's project "Guitar" but I need some help. Just plugged in a used Marshall DSL401 that I purchased and I am having a couple of issues. I wanted to know if they were major or if it just needed some new tubes and general service. The first thing of note is it's noisey. With my guitar volume all the way down, or even unplugged, I hear a real lot of swooshing sound in the background that gets worse when I increase the volume. (Power amp Tube?, Biasing? ???) I know it's a Marshall, but the clean sound is really thin and has no low end at all. Hitting lower notes just farts. Could this be related to the first problem, or is there maybe a bad speaker as well? Any input would be greatly appreciated. I knew the amp might need to be serviced so I am just trying to pin down exactly what I need to do. Because I will probably learn how to do it myself on this amp. It's okay to just poke around in there with a screwdriver right? Any links or sources of Tube amp service and diagnostics would be appreciated as well. I'll check on my own as well of course. But if someone knows a good place to point me that would be great. Quote Link to comment Share on other sites More sharing options...
