The 6DJ8 (European type ECC88) is a dual triode tube with a 6.3 V, 365 mA heater and a B9A (Noval) miniature 9-pin base. The high-reliability version is the 6922 aka E88CC (Tek P/N 154-0371-00) or 8416 (with 12.6 V 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.
The 6DJ8 and its variants are used extensively in many Tektronix instruments of the tube era.
As of 2012, 6DJ8 tubes are still manufactured and used and new old stock (NOS) 6DJ8s can also be obtained easily.
The 6DJ8 is well regarded in the tube audio community, leading to exaggerated prices and occasional cannibalism of classic Tek gear.
Tek part numbers:
- 154-0305-00 = 6DJ8
- 154-0195-00 = 6922
- 154-0413-00 = 8416
