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.

All of the above responses are correct. Before you start changing out tubes, I suggest you draw yourself a diagram of tube sockets and number them. Next, label your tubes alphabetically. So, 'A' is in hole '1', etc. Also this will help if you think you might get the wrong tube in the wrong hole.

I know this sounds a bit redundant, but if you have never done this, you might feel more comfortable and you might not be encouraging any regrets.

First, I would swap everything to see if the sound moves from one channel to the other. Then I would start swapping tubes back, one at a time, until....Bingo!
