Key Features & Specifications
- Design & Compatibility: Built to mirror the classic Western Electric 300B, featuring a large-shoulder ST glass envelope, an 8-course directly heated filament, and a 40-watt plate dissipation. Its static DC characteristics and plate curves match the original specifications, allowing drop-in compatibility with most vintage and modern 300B amplifiers. [1, 2]
-
Standard vs. Gold Grid Versions:
- Standard EH 300B: Uses traditional construction and a white or ceramic base, prized as a rugged, great-sounding OEM workhorse.
- Electro-Harmonix 300B Gold Grid (Gold Pin): Upgrades the internal grid wire to gold-plating, which reduces grid current, improves bias stability, extends tube life, and adds gold pins to prevent oxidation. [1, 2, 3, 4, 5, 6]
- Sonic Profile: Known for a balanced, dynamic presentation with a strong, clean lower end and musical detail. [1, 2]
