0G3 VR Tube

The 0G3  (European: 85A2) (P/N 154-0291-00) is an 85 V voltage reference tube with a miniature B7G 7-pin base. It is very similar to the 5651 but has a wider current range, specified as 1–10 mA, and tighter voltage rating, 85±2 V at the recommended 6 mA vs the 5651's 87±5 V. Socket pinout is identical.

Note: The designation is 0G3, the leading zero indicating a tube without a heater, although this is often mis-printed as OG3.
