Best 12AU7?


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

@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.

Agree Telefunken are the best I have heard for a detailed brighter sound.  Rca cleartops are an amazing value and sound extremely good on the brighter side as well. Can’t go wrong with either.
