Nice tube in a SE amp
I plugged this tube into a single ended amp that I had built for KT88's and adjusted the current and voltage to get in the right ball park. I was pleasantly surprised at the quality of the bass and the highs, both of which, I had thought were pretty good before. Now there's way more solid feel to kick drums and stand up bass and cymbals really get the whole shimmering thing going. I'm running them into a pair of Altec model 19's or 604-8G's. All in all, they're keepers.
