Pinout

Pin # Assignment
1 G2 Red Pin
2 G1 Red Pin
3 Heater (F1)
3 Red Pin
7 Heater (F2)

Note: If you only see one assignment or reused pin for G1 (or G2), it means there is only a single G1 (or G2) grid shared across all cathodes. This is called "common G1" (or "common G2"). In this case, when using a Universal Adapter (UA), you only have to hook up one G1 (or G2) lead on your tester to connect all cathodes' G1 or G2 properly.
