Best 12AU7?


What is the best 12AU7 or equivalent? NOS or new production. I like brighter sonics with good treble air. Thanks!

12au7 in my integrated are phase splitters. My fav is Amperex 7316 long plate. But I just bought a pair  NOS Telefunkins...I am liking right now...probably gonna go back and forth for a while. Basicly a cheaper version of the famed G73-R

I'm using the Tung Sol 12AU7W / 6189 now. I find it bright, but in a very nice, warm and fat way! I keep coming back to this tube.

@olds1959special Not a fan of the Tung Sol re-issue when compared to NOS. But…they are probably one of the better new tubes. I also really like the RCA 5814a TM BP. Top 3 for me but I don’t see it brighter as you said you preferred. It more neutral  towards warmer to me which I prefer. Other good ones I like are Westinghouse ‘60’s long Carbon Plate and Raytheon ‘60’s 5814a TM BP.
