It's widely regarded as the current benchmark reissue 6550, used as stock/upgrade tubes in gear like Audio Research, VTL, VAC, Rogue, Sonic Frontiers, and classic bass/guitar heads (Ampeg SVT, etc.). TubeDepot "Perfect Pair" originally sold as a factory dual-parameter (plate current + transconductance) matched quad.
