Hi,
I have a 5:25 Express (the original model, not the Plus) and I'm getting a lot of power amp noise. The noise is a scratchy, static-y sound. I know it's the power amp, because I can turn the preamp master volume to zero, and switch between clean and burn, with no effect. I have also put a patch cable into the FX Send but not put it into the return, so the whole pre-amp is not connected.
Thinking it was likely power tubes, I replaced them, and I also replaced the preamp tubes for good measure, but this has not affected the noise. The signal when playing is fine, and the amp works perfectly otherwise, but the noise at rest is just very irritating for when I practice or am playing quietly. I do think it's above what is normal, certainly for all the other tube amps I've used.
Does anyone have any suggestions?
