GT-6L6-R (B) Duet
Russian made, same as the 5881, but matched in the GT system. These are a very sturdy and reliable tube, with slightly less power and a more aggressive edge when pushed into distortion.
These are the tubes that are used by Fender in amps that use 6L6 tubes and DO NOT come from their Custom Shop. These are used in the Hot Rod series, Blues DeVille series, Pro Tube series, BF reissue series.
The GT 6L6GE is used in the 57 Tweed, Vibroverb and Vibro King amps.
