Not as good as the original CV-181-T
This is a good tube, but for a bit more money the CV-181-T is the better step. I have used this while tube rolling 6SN7's and feel it betters the Tung-Sol, the RCA red base and all the other very expensive 6SN7's. It does need about 100 hours to burn in, but it has every aspect covered. Amazing tubes.
