Modeled after the vintage RCA 6L6GC "Blackplate" the Sovtek 6L6WXT+ features larger plate dimensions and improved grid structure for increased power handling capabilities. The 6L6WXT+ also features mica spacers with metal springs to eliminate tube rattle and microphonics. The Sovtek 6L6WXT+ yields a 20% higher output than the Sovtek 5881WXT and offers superior tone and overall performance. 
These were originally sold in bulk cases without retail boxes for OEM use in new amplifier production so they will ship in generic white tube boxes.
