Product Details

Electro-Harmonix 300B EH Vacuum Tube Quartet Platinum Matched
A triode maniac's dream come true! Ultra-long life, top-quality construction, and superior sonics make it the finest 300B available today. Like the original Western Electric 300B, it has the 8 course directly heated filament, 40 watt plate dissipation and classic large shoulder tube glass. The 300B EH'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. Matching power tubes for equal current draw is important for maximum performance. Electro-Harmonix's platinum matching process consists of a 24 hour tube burn-in period followed by a bias (plate) current measurement in milliamps to ensure accurate matching.
