I just picked up my first tube amp (a twin) and have found there to be periodic crackling and pops. It is nothing major and I only notice it while the amp is on while I'm not playing while practicing. I heard the same pop sound when I tried out the vox tube powered preamp, however much more dramatically. I told the clerk and he brought me a different unit that did not have that problem. I'm wondering if it's a tube issue and I'm hoping it's fixable. Thoughts?
BTW; I used that vox preamp for a musical gig I had where I went into the house direct. It has a nice sound, was only $199, and completely beat the crap out of the red line 6 pod unit the company provided. That pod and another pod both broke on the road. If anyone finds themselves in a similar situation, I definitely recommend it.
