Groove Tubes GT-EL34R - Russian Power Tubes - Medium Duet

These NOS tubes are unused, and still in their factory box.
The GT-EL34R Power Tubes Duet is a Russian-made pentode that's standard  issue on many UK amps and has great durability. These tubes feature a  slightly harsher breakup and less high-end clarity than European models,  giving them a distinctive combination of classic and modern tonality.  Available in pairs.
