I can play my new DSL40 on the 20w setting on the clean 1st channel for 30-50 mins and the sound will shut off (does the samething on 40w setting). Crunch on 1st channel will be muted and the second channel no problem with sound at all. I've taken it back to the store and of course can't get it to reproduce the problem. I've checked my power connection, no reverse polarity, neutral and ground all fine. I do have 126 volts at the outlet. My power company checked the line coming to the house and had 126v on each leg and no problems with the ground and neutral. The shop that I purchased the amp is running 123v. I cannot find anything on this site to tell me the voltage tolerances of the DSL40. Is this problem an over voltage issue or something else?

Hi there

I´ve recently bought a dsl40c amp, and the first times i used it the amp  worked just fine and had a great sound! 

After 2 weeks of  regular use the amp started making a popcorn-like sound but I thought it was normal or that it was due to the valves beeing new. More recently it started making this interminent sound: When I play gently it sound normal, but when I push it the sound drops .

The amp is still covered by  warranty but the shop where I bought its 250 km far from where I live, so if someone can help me out I would be very appreciated!!

To use my 8-ohm cab with my DSL 40C, do I need to unplug the dedicated 16-ohm plug from the back of my amp? Thanks

Hello, just purchased this amp, play almost everyday and love it. When I first got it (playing for hours) I noticed there was a crackling/scratchy... almost like a loose connection sound from the amp, I played around with the cord and it didnt happen again until tonight, about 2 months later. This time it didnt just go away so here are my observations:

I was on full power, maybe 2 on volum, on the clean channle with gain. It seemed fine on e, B, G but on D is where it happened, didnt matter what fret and it seemed to do it on the A and E as well but not as much, I switched channels it did the same, I went into standby and switched cables, same thing, I plugged the guitar in another amp and the issue did not happen, I plugged the guitar back in to the marshal, the crackle was still there. I turned the amp off, put it in half power, turned it back on and no crackle. I turned the amp off, did a few things around the house. came back, put the amp back to 40W, turn it on and it is fine.

Thinking it happens if it gets warm? I have never had a tube amp... so im not sure what signs to look for with regards to a tube going bad... I'm not sure if originally leaving it at 40W and restarting it if it would have been fine. I will try and recreate and see what happens. Any thoughts?

 

UPDATING:

The foot switch made no difference. I'll move it to another room tonight. I have included a recording if anyone wants to hear it. In the recording you here the noise, I hit the B string 3rd fret... and it goes away, i then hit the D string 12 fret and you hear it come back.
