ELECTROHARMONIX - 300B TUBE Matched Pair

Ultra-long life, top-quality construction, and superior sonics make the Electro-Harmonix 300B the finest available today. Like the original Western Electric 300B, it has the 8 course directly heated filament, 40 watt plate dissipation, classic large shoulder tube glass, and are available singly or in precision matched pairs. The Electro-Harmonix 300B'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 amp and realize the finest performance of any 300B made today.
