    I recently bought a 1968 ampeg b15n. I have been getting intermitent static off and on since I got it. Sometimes it sounds like it should, nice clear tone w/ no static then it starts for a period and then stops. There is no pattern. I have put all new tubes in it and it still does it. Are there any tube amp guys that could give any suggestions on this? Thanks.
     
  2. Check its coupling capacitors. There's one in the negative feedback loop that has a tendency to get out of whack and do exactly what you describe.
     
  3. Possibly a bad speaker out jack?

    Thanks for the help. Speaker jack I can check. But I think it probably is the cap you spoke of psycho. I still have a few days left under the warranty so I'll take it back and let them fix her up.
