that tube would only make noise as I turn up or down the VC, once I stopped turning the VC it was dead quiet. Then after a few months of using it like that it started to make noise without moving the VC, it was a little crackling noise. I would tap on the tube to stop it from making noise. Then I moved the noisy tube to the left channel and the good tube from the left to the right, it did it with the bad tube the same thing in the right channel. Like I said at the first post I thought it was a bad VC that needed cleaning due to oxidation but it wasn't, it was the tube that why it was so weird.When I checked it with the scope after building it with 1khz and 10khz square wave and sinewave it was all good, no ringing or oscillation. That scratchy noise was always there from the beginning, I never saw it on the scope when I turned it up slightly when measuring it. All I know it was the tube and with the new tubes in there its all good even with the scope measurements. Well, its all fixed now and working fine. I was just wondering if anyone else had anything similar to what I had.
