JJ EL34 or E34L

I have read that the JJ tubes with the E34L logo will produce more power than one that has the EL34 print. I do have two quads of both,however one of the tubes of the E34L camp is bad.If the above is true will a tube from the EL34 group make a audible difference? My Anthem amp has seperate bias pots for each tube. Any advise from the group will help me greatly.

You are correct. The E34L will run at a higher bias. I do not run these or have an Anthem. If you run them at the same V I bet they are very similar. Try it out. You will not hurt anything. If you have not already done so I would ask the same question at the audio asylum.com tube section. Lots more EL34 folks there who might have experience right on point.

South43. I have heard that you have to bias the E34L higher than the EL34 likes to go to really make them get up and go. Don't ya love tubes!
