Johnbonn, for many amplifiers the 6n3ce is a direct replacement. I'm not sure about your amp. Please let me refer you to Jeff Days blog, jeffsplace.me/wordpress/ he writes for Positive Feedback and 6 Moons as well as others. I was originally turned on to this tube via his blog and found that his comments to be true in my Primaluna Dialogue 1 and Cary v12. Go to section where he talks about the 6n3ce in his Leben amps against various EL34, other 6L6 variants, KT 66, KT77, KT88, KT90s and so on. Another good source for information is Tube Guru Jim McShane who is authority on this tube and has them in stock, though supplies are dwindling fast. So, I'm cutting my own throat here with the recommend, but I believe I bought a lifetime supply. Best.
