This is a high-end absolutely fantastic rectifier tube, I bought the smaller cheaper model first and it was also amazing but this is worth the 10 extra dollars. Rich deep tones, added punch and resonance. JJ tubes are always my first choice, I am extremely happy that I went after this one, loved it so much I'll replace my other rectifier tube with another one of the same. I'm running a B-52 at 100 triple rectifier amplifier head and 2x12 combo of the same... Both I have completely retubed with JJ's from Ruby tubes.
