    ruby tubes EL34SBTR
  

*by D***. on Reviewed in the United States on January 4, 2014*

These tubes ( china) came stock in my Marshall DSL40c. they have a great low end . Tried others but these sound best in this amp to me.Make sure to set bias after installing or do what i did and buy 4. Bias one set and the other matched set will be good to go when needed.
