Description
Groove Tube’s EL34 Mullard Reissue pays tribute to one of the most revered power tubes in amplifier history. Rather than approximate the general EL34 formula, Groove Tube went straight to the source and reproduced the classic XF2 dual getter variant — the version most associated with the tone that made this tube a benchmark for both hi-fi audio gear and guitar amplifiers.
Sold as a matched duet, these tubes are built for players and techs who need reliable pairing in push-pull output stages where balance between tubes directly affects headroom, breakup character, and overall amp stability.
