| Pin # | Assignment |
|---|---|
| 1 | Heater (F1) |
| 2 | G2 Red Pin |
| 3 | G1 Red Pin |
| 4 | Blue Pin |
| 5 | G2 Blue Pin |
| 6 | G1 Blue Pin |
| 7 | Red Pin |
| 11 | Green Pin |
| 12 | G2 Green Pin |
| 13 | G1 Green Pin |
| 14 | Heater (F2) |
Note: If you only see one assignment 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.
