Popping/Crackling in DT25 even after tube replacement and biasing

Recommended Posts

I got my DT25 tubes replaced (both preamp and power) with the following tubes below, earlier this week. I confirmed that Line 6 recommends these tubes. The tech had also biased the amp post replacement.

However, the amp is making crackling noises in Class A/B mode but NOT in Class A.

 

Thoughts?

If it's not the tubes, then it can be one of two things. And that will have to be serviced by

an Line 6 authorized service center.

Does it crackle without anything plugged in? I had similar issue and found out it was a dodgy instrument cable.

Wondered that myself, but it only occurs with hummers.

If it was the cable I would expect it pop and crackle on both hummer and single coil. 

 

Unless there's something odd with the cable ground, that it would only occur with the humbuckers.
