Peavey Windsors are.....

[Metal Overload]

i think i have this problem with mine too, do you play it loud? i only played it loude once and didn´t notice it, but in lower volumes you can feel it.

Yeah I also played it pretty loud with a dummy load.
I think it has to do more with the input stage rather than the output, but I'm not sure.

That's why I ultimately stayed away from the Windsor ITE. They are great sounding amps but it seems like every second dude who gets one experiences some kind of problem out of the box. Seems like Peavey's quality control ain't too great lately...

Wasn't it the same case with the 6505 (or 6505+)? But that was because of shoddy factory preamp tubes.

 

[Jarkko Mattheiszen]

They seem to be gone again :/ And yeah, check the tubes. Mine came with a faulty power tube.

 

[Skaldir]

I'd like to try that. Which tubes to get? Maybe I could kill two birds with one stone and get some better tubes.
Is the warranty lost when I change tubes?
