User Feedback for Sophia Electric™ 300B Mesh Plate Tubes
By Mr. Vince

The Sophia Electric 300B tubes have the best harmonic balance of any 300B tubes I have used and I think I have tried them all including the Westerns. These mesh plates have no one dominant characteristic in that they have fine extension at the extremes while maintaining a balanced and sweet midrange. I run them fairly hot at 80 miliamps but have had no problem with them. Highly recommended.
