The Electro Harmonix EH 300B is an excellent choice.
The 300B entered the market in 1938. That it remains in production today is a testament to its superb quality.
Ultra-long life, high-quality construction and superior sonics make the Electro Harmonix 300B a top choice over 300B types from other manufacturers. Like the original Western Electric 300B, it has the eight course, directly heated filament, 40 Watt plate dissipation, classic large-shoulder tube glass, and is available in precision matched pairs and quads (as you see here). The 300B EH’s plate curves and static DC characteristics (plate resistance, transconductance, mu) also exactly match the Western Electric originals for superior performance in any vintage or modern 300B amplifier.
These valves are factory matched for mutual conductance and current, with their test values and results printed directly on each valve box (as you can see in the product photos).
Made with genuine care, the EH 300B is the perfect choice for replacing or upgrading your quality hi-fi amp.
Includes a 180 day from receipt warranty (excluding user-caused mechanical damage) for peace of mind.
