How much is the Cryo Svetlana and where can I find them? Is the KT77 a drop-in replacement for the EL34?
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!
