During the first few minutes my amp is on and on channel 3 it makes a hissing/popping noise that sounds like a vinyl record before the music starts. Is this normal for DR's or Tube amps? This is my first tube amp and I am trying to figure out what it par for the coarse and not. I have checked cables and gently tapped the tubes to see if one was microphonic. I also turned all the pots on the 3rd channel but that didn't make a difference. Thanks in advance for any help.
