Hey Everyone, I have a DSL 100 that has volume issues on the green channel clean, let me describe. I'll turn on the amp and let it warm up for 5 min or so, I'll play the green channel clean without a problem for 10 min, then the volume drops by half or more and fluctuates up and down, i'll push the crunch button and the volume often comes back, this goes on for 30 min then i can play for hours without any issues. this only happens on the green channel not the red. i changed all the tubes and checked bios but I'm still having the same problem. I almost suspect there is something loose or needs re soldering as sometimes pushing the crunch button doesn't get the volume back i'll give it a smack on the top and the volume comes back . Thanks in advance for any help in diagnosing this .
