Update your amp with Ruby replacement tubes

The classic tube for amps known for the “California” sound, like the Fender Super Reverb and Twin Reverb, the 6L6GC high-power beam tetrode tube is known for clean punch, high headroom before breakup, tight bass and mids and a high-end response with plenty of “chime.” This matched pair of Ruby 6L6GC tubes is a premium replacement for the amps mentioned above, as well as many others. All Ruby power tubes are labeled with precise matching measurements for transconductance and plate current. Matching those parameters ensures long tube life and optimal performance.


  • Matched beam-tetrode power tubes
  • Premium direct replacement for any 6L6-based amplifier
  • Base labeled with precise plate current and transconductance ratings
  • Manufacturer’s 6-month replacement warranty
