What about TAD tubes? I've heard good things about them. Probably gonna get a set. Might be a good alternative. Though I haven't heard either. So I can't tell.
Yep I can get TAD as well. TAD is a company similar to groove tubes, they are simply another brand tube relabeled with a different logo. But from what I hear they have a pretty good selection process, which yields good sounding long lasting tubes. I might try some of their short bottle 6L6's next.
