From my experiences the JJ Tesla's had the most bass and the sweetest midrange. ( of current tube productions ) The Svets lacked in bass, and I thought the Electro-Harmonix were just plain blah. But I suppose it depends on the associated equipment.
EL-34: JJ Tesla or Electro-Harmonix?
Between these two cheaper brands which do you guys recommend. I'm looking for decent tubes to go into an amp I intend to sell - will keep the nicer tubes currently in it for myself. Also, if you know of other brands in the $40/quad range please let me know. Thanks!
