Groove Tube GT-EL84-R Power Tubes
GT-EL84-R Duet Russia EL84, Good quality, long lasting type with a slightly aggressive edge when pushed into overdrive. Most common low power pentode, popularized in early Vox AC30 amps. Rediscovered by Matchless amps and now currently used by nearly every tube amp company. Quick, soft overdrive distortion, great for recording but usually too low volume for live gigs.
