Pinout

Pin #	Assignment
1	Focus (G4)
3	G1 Green Pin
4	Heater (F1)
5	Heater (F2)
6	G1 Blue Pin
7	Red Pin
8	Green Pin
9	Blue Pin
10	G2 Red Pin
10	G2 Green Pin
10	G2 Blue Pin
11	G1 Red Pin
13	Focus (G3)

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.
