The high-reliability version is the '''6922''' aka '''E88CC''' (6.3 V, 300 mA heater) or '''8416''' (12.6 V, 180 mA heater).


With 15 mA of plate current, 90 V plate-to-cathode voltage, and −1.3 V grid-to-cathode, the 6DJ8 provides 12.5 mS of transconductance with a plate resistance of about 2.5 kΩ.

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.
