I've tried all the currently manufactured EL34 types, including the Mullard reissues (had one go bad after two months, was arcing badly and blew several fuses before I said "nuts") but by far the KT77 tubes offered by Rogue Audio are the best I've had in my system.
Mullard EL-34 reissues
Anyone tried the Mullard EL-34 out put tubes. I have heard phenomenal reviews from two sources. One being upscale audio. i am a little hesitant based on EL-34 tubes reputation for being soft at the extremes... What amp are you using. I have the TAD-60s and replaced with the new Tung Sol 6550s...
