I been getting this buzzing humming noise coming from my Z-lux so I tested my preamp tubes. When I knocked against the 12ATX7 tube the buzzing and humming increased. I checked with the reverb off and on and it still did it. Im thinking maybe that tube may have went bad? Not sure its like a humming buzzing noise.

Could be a tube but also make sure you don't have a cell phone near the amp. That also can cause a buzzing - happened to me last night. As soon as I moved the phone the buzz went away.

No its not the cell phone its def coming from the amp. Thanks I have a place in town I can pick up that tube from its a JJ I will swap it out and hopefully fix it.

Problem solved it was the 12ATX7 tube it went bad. Got a JJ in there now amp sounds fat! If it happens again, consider installing a NOS 12AT7. Fixed a similar problem with my MAZ 18's reverb.
