Ignore the hype
I guess it depends on what type of amp this tube is being used in. How it's advertised as robust and compared to a JJ 6V6, one would think this is a good tube in a single end class A 50s style amp. I bought one of these from another dealer and the bottle was attached to the pins very crooked. Then the bottle broke off from the pin casing. I figured I try another and bought it from tube store. It sucks for sound. I'm going back to JJs.
