The BiValve-30 gives each power tube its own cathode-bias circuit and its own transformer winding. This permits the BiValve-30 to run two completely different tube types, creating a new dimension within tube amp sound. Useable tubes include 6L6, EL34, 6550, KT90, KT88, KT77 and KT66. With the amp in “LoV” setting you can use the 6V6 power tube for reduced output power.\u003c\/p\u003e\n\u003cp\u003eLikewise, the two preamp tubes can be any combination of 12AX7, 12AT7, 12AU7, 12AY7, or 12AZ7.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote: After close inspection, this amplifier has wear and tarnishing throughout.
