I have a Marshall DSL100 head I am having some crazy issues with. About a month ago I was playing at our practice site (new place) and all of a sudden the volume just went out. I noticed that my effects loop wasn't receiving a signal either so I unplugged the effects loop but still nothing. I powered the head down and ran the power to another outlet. I powered the amp back up and everything worked again but everything was a little fuzzy and the volume wasn't quite up to normal. The next day, I played through it again at home and everything worked fine. I played a few days later at the practice spot again and everything worked fine for about ten minutes and then I had a repeat, volume cuts out and after about five or ten minutes it comes back, a little fuzzy at first but then is totally fine after playing for a couple of more minutes. I was thinking it might be the power or preamp tubes so I replaced them all and rebiased the power tubes. To no avail, still having the same issue. I've tried just running the guitar straight into the head with no effects, different chords, no effects loop hook or anything and the problem still happens.
Here's the symptons in a nutshell;
*volume cuts off after being played for about ten minutes
*no signal goes through the effects loop
*no hum or hiss out of the cabinet
*after a few minutes the volume slowly returns, fuzzy and distorted at first
*after a few more minutes of playing the volume fully returns and the problem does not occur anymore while the amp is on, or even while it is still warm and power back on
Any thoughts or suggestions would be greatly appreciated!!! I am taking to a tech tomorrow but wanted to see what others may have experienced or what it might be.
thanks!!!
