High gain preamplifier tube with ultra low noise and detailed, musical tone. Unique spiral filament eliminates filament to cathode induced hum common on amplifiers that use AC on the filaments.
This Russian tube is our favorite for hi-gain amps… or really any amps. It’s evenly balanced sound gives guitar amps a full frequency response but with a bright edge needed to cut through the mix when your amp is screaming at stage volumes. We stock this tube because it works in almost every situation.
