RE: New Tubes (6CA7)--now bias too high

Thanks, Peter. I didn't think there should be any bias issues either as these are touted as a drop-in replacement for EL-34's. Unfortunately, the reading does not drop after a few seconds and continues to rise slowly. I haven't kept the amp powered on for more than a few minutes with these for fear of damaging something. I replaced the tube sockets a couple of years ago with ceramic ones. When I swap EL34s back in I am able to bias them fine. I'll try you re-tensioning trick.
