One thought on “Tung-sol 12au7 Black Glass

  1. A superb tube. Very well balanced. Very strong Bass. Clean and articulate mid-range. Very bright and airy HF. Sound stage is fantastic – three dimensional, but yet well defined. This tube comes very close to Telefunken smooth plates. I compared it to RCA clear top and Amperex and this tube is a clear winner. It’s getting very expensive though. If you like very detailed, very airy sound with a fantastic sound stage – this tube in 12au7 family is it. Nothing else comes close. Tried it in two amps with the same results.
