The Electro-Harmonix 300B Gold Grid Power Tube is a directly heated power triode vacuum tube manufactured in Russia by New Sensor Corp, designed as a reliable, high-value alternative to the classic Western Electric 300B. [1, 2, 3]
Key Specifications & Design
Design: Mirrors the classic Western Electric 300B with an 8-course directly heated filament, large-shoulder ST glass envelope, and a 40-watt plate dissipation. [1, 2, 3]
Electrical Match: Matches the plate curves and static DC characteristics (plate resistance, transconductance, and μ) of the original 300B, making it a drop-in replacement for vintage and modern amplifiers. [1, 2]
Standard vs. Gold Grid (GG) Version:
- Standard 300B: Built as a rugged, balanced OEM workhorse with a clean lower end and good detail.
- Gold Grid / Gold Pin Version: Features gold-plated grid wire and gold-plated pins, which reduce grid current, improve bias stability, prevent pin oxidation, and extend overall tube life
