Groove Tubes EL34R Duet

Power Amplifier Duet (2 Tubes)

Manufactured in Russia, the GR-EL34R has now become almost the standard tube for many of today's British Amps and is in principle a modified copy of the old Mullard tube. The GT-EL34R tube is powerful, offers a straightforward frequency response and has a unique sound with good assertiveness. In distortion mode it is generally quite aggressive and slightly harder. The sound and particular reliability are the main reasons for the wide use of this tube.

  • Hard basic sound
  • Durable
  • Reliable EL34

Good experience!
Marcus348, 02.11.2010
For over 20 years, I've fed my Laney Pro Tube Lead with Groove Tubes and find the dynamic pressure that they are developing just great. I had already used the EL 34 from EHX, or Sovtec, which were too vintage for me (for example, Black Sabbath with my Laney). The tubes heat up nicely and make a juicy punch when you need it, otherwise the dynamic response of my amp is excellent in every gaming and gait with the Groove Tubes.

EL34 for my triple rectifier
Guillaume1675, 22.02.2014
I replaced the original 6L6 of my triple-sided MESA with these GROOVE TUBE EL34 R lamps.
These are "middle gain".
I only put 2 pairs instead of 3 => (2 slots of lamps remain empty)
That suits me perfectly.
No particular problem. (I also changed the PRE AMP lamp kit at the same time)
