Description ▴

The return of a classic… What if the best sound was achieved decades ago? In 1938, Western Electric manufactured the first type 300B electron tube. It was a breakthrough power triode, but in those days it hummed away from behind a curtain in early Hollywood sound systems.

The same things that served moviegoers back then—low noise, ultra-long life, sonic purity and warmth—made it a standout tube for music lovers and vintage audio collectors as the years passed. Deep into the age of the transistor, communities around the world in search of true, original, high-fidelity sound rediscovered the 300B and its exceptional performance. New amplifier designs brought the tube front and center, its customary yellow lettering on proud display.
