Hi Larry,
I had the EML mesh 300b in my Frankenstein for about a 3 week period a few years ago, Its sonic character was just as you described, very open, airy yet delicate and nuanced. I really liked that tube. Jet is right however, it didn't last long in my amplifier for the reasons Jet stated. The EML XLS is right at home in the Frankenstein by comparison as it's much more rugged and robust. For more conservative run 300b amplifiers the EML mesh plate 300b wound be one to strongly consider in my opinion. This tube is a "true" mesh design unlike the Sophia "mesh plate" versions.
