The new JJ KT66 tube from JJ Electronic. This KT66 tube is rated to handle 550V of plate voltage and screen voltage. If your amp has "bear trap" tube retainers they will have to go because of the size of the tube's base but also the bear trap clamp will ground the metal base to the chassis and cause a malfunction.

These tubes have been paired for optimum power and tone.
