+{{Tube aging reference}}
+As of 2023, 6DJ8 tubes are still manufactured and used, and new old stock (NOS) 6DJ8s can also be obtained easily.
+However, the 6DJ8 is sought after by [https://www.urbandictionary.com/define.php?term=audiophool some in the tube audio community], leading to exaggerated prices and occasional cannibalism of classic Tek gear.
