About this gear
The ER300B-Mo is ELROG's premium take on the legendary 300B directly heated triode, hand-built in Germany with a tungsten filament and a molybdenum plate structure for greater durability and thermal stability than vintage-style 300Bs. It's aimed at owners of single-ended triode amplifiers who want the classic 300B midrange warmth with tighter bass and longer service life. This is an investment-grade tube for listeners chasing the last word in tonal purity from their SET setup.
