I have around 400 hours on my new pair of Stradi 5U4G's. So far they have performed flawlessly and they sound fantastic! They have the look and feel of NOS tubes made in the golden age. I'm verry impressed with this tube!
I’m saying a little prayer and hoping third time’s a charm! The approx. 250 hrs between the first two tubes were hands down, glorious! John has been very communicative and fair about all of this.
