I have to agree that the Ei's sound great.I've tried a number of NOS types in my CAT, but the dynamics, drive and tonality of the Ei's have been the best so far. Jim
I have also tried many NOS and new 12ax7 and I guess I have to now try the Ei tube. I have found that the Svetlana 12ax7 is a very nice new tube and think you can put it on your short list to try.I have tried numerous nos 12ax7 and remain using at this point the Svetlana.
So far I havve tried JJ , Svetlana, EH, and now those same Parts Express Ei and the Ei are the clear winners, it was obvious within seconds of turning on the amp,they just get it right.
