User Feedback for Sophia Electric™ 300B Mesh Plate Tubes - By Mr. Mark Katz (2002)

I just was writing to let you know how well the mesh plate 300Bs are working in my SE amplifiers. The sound is clear, detailed, extended in both bass and treble, maintaining the magical midrange that 300Bs are famous for. The sound is quite dynamic. This is a tube that does everything well, plus the classic globe shape looks good. I've been running them several hours/day for the past 2-3 months and am quite pleased. This is a step up from the Electro-Harmonix, my previous affordable reference and much more listenable than the new WE 300Bs. Congratulations on your fine tubes.
