Electro-Harmonix 300B Gold Grid
Long life, top-quality construction, and great tone make it one of the finest 300B tubes available today. Like the original Western Electric 300B tube, it has the 8 course directly heated filament, 40 watt plate dissipation, classic large shoulder tube glass, and are precision matched. The EH 300B tube's plate curves and static DC characteristics (plate resistance, transconductance, mu) also exactly match the originals so you can drop them into any vintage or modern 300B tube amp. For the money the 300B EH tube is a fantastic tube!
Be sure to read the great 300B tube review and comparison from the Wall of Sound.

Value Champ in my comparison review
by Noam Bronstein
I recently reviewed the whole fleet of 300B tubes, and spent a lot of time with the EH-300B Gold Grid. This is a great sounding tube. It wasn't "the best: at anything, but it had no weaknesses either. And the pricing is excellent compared to the others. For my full review see my website, www.wallofsound.ca
