Is the noise in one channel or both? The most common causes of intermittent noise, a bad tube or a bad connection, are often channel-specific. If the noise is in both channels, then look at any small-signal tubes shared by both channels. If the circuit is all dual-mono, then a problem showing up in both channels wouldn't be caused by one bad tube.
Help..................... I am a little worried.
I am hearing a strange sound in my system that sounds.......well it's hard to discribe but, maybe a coughing, crackling kind of thing. It's not real loud, and I only hear it when I am not playing music. I have had some problems with my power amp (VT-200) blowing some tubes in the past, so I am thinking it might be something with it. The thing is ARC just went over it (about 2 months ago)and said everything is fine and installed all new tubes. I wonder though "Is everything fine"?
Does anyone have any ideas for help on this one. Could it be something else and how do I figure out what's causing this. Needless to say I am a little worried........ If it is the amp shipping this thing from TX to MN. isn't cheap.
