RE: Hitachi 6SN7GTB question: Top getter vs bottom getter tube


As far as getter location, I only pointed it out as a visual way to differentiate this Hitachi 6SN7 from the other more common version, as there appears to be just these two types of Hitachi 6SN7's. The top getter tube seems to have been made with black or grey plates, and also has a Toshiba version that appears identical. I think all would agree that no matter how identical tube construction appears between different manufactures, the sonics can be very different.

I have not heard the top getter Hitachi and the more common ITT/Hitachi branded one of the same tube, but most owners say it leans towards a warm overall presentation. I did find two comments from owners of the type I just purchased and their take on the sonics is much like mine. Both those reviewers said this bottom getter black plated tube is one of their favorites, as it in likely to become one of mine.
