I was comparing 12AX7 tubes for my V1 and mistakenly put in this Tung Sol 12AT7W. I knew something was up by the significant drop in volume but stuck with the comparison. I felt that for the first time in comparing tubes I was hearing my guitar instead of electronics. There was more definition than other tubes. There is less drive than the TAD 5751 and more clarity. It's similar to the TAD 12AT7 but a little brighter. I think anyone trying a 5751 might find this tube to be worth considering.

I am very happy with the tubes they have worked flawlessly in my fender 65 reissue twin reverb. Customer service was fantastic also .

Works great, although the first one I received was very noisy and I exchanged it. The second one worked.
