This is a matched quad of new in original box Mullard / RTC EL34 audio amplifier tube. All EL34 are Made in England by Mullard and same batch (codes: Xf3 B4E4). These are single ring getter and slotted plate EL34. Tested OK by TV-7D tube tester and the reading is 50 per tube roughly (pass = 30 = 65%). I installed the tubes into Marantz 8B tube power amplifier. Tubes are better than many current productions of so-called HiFi EL34. Seller ship worldwide. Note: Seller will ship this item to the buyer within 10 business days after receiving cleared payment. Normally, buyer will receive the tubes 3 to 4 weeks later (delivery time for buyers in Argentina, Hungary, Jamaica, Indonesia, Turkey, Russia, Italy, Mexico and Brazil is longer very much. Sometimes it will take 90 days or more.). Please feel free to contact me if you have any question.
