SED "Winged C" 6550 Pair

Based on the GE 6550, engineered with improvement in mind. Excellent upper detail without any harshness in the highs. The SED 6550 is THE stock 6550 choice for many tube amp manufacturers. New cathode materials for increased performance, gold plated grid, tri-plate anode make this one outstanding sounding 6550.

The midrange quality you'll experience from these is quite impressive. Recommended for those that enjoy jazz vocals and similar genres.
