Groove Tube GT-EL34-R Tube

Groove Tube Gold Series GT-EL34-R Matched Power Tubes High (8-10 GT Rating) Duet

This Russian-made pentode is standard issue on many UK amps and has great durability. As with most Russian power tubes the break up is a bit harsh and they lack high end as compared to the true European models. Unique sound, slightly edgy distortion when pushed hard. The most reliable of all in this family.
