  I have settled on E-H 6CA7s in my Rogue Atlas. They sound great to me.

  My favorite 6CA7 is the Sylvania/ECG fat bottle version. The late RCA branded tubes are the same as well. It has great bass. The highs are not the best but it is a good sounding tube. Reliable as well. Unfortunately they are now valuable do to being sought after by the guitar players.

  6CA7s are beam power tetrodes. EL34s are power pentodes. They are electrically equivalent, but don't sound alike.

  US made NOS is a good place to start in the "beamies". Check AA sponsor Jim McShane's pages for stock. Try the other tube selling sponsors too.
