CR-40 Datasheet 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.
Notes
The A20JMP10X tube inside is directly interchangeable with the higher TVL M20JMP10X tubes of the 8042Q, 8045Q, and 9L3 PVMs and will result in a dramatic increase in scanline definition and detail. Inversely, if you replace an M20JMP10X with the A20JKU10X, the TVL will decrease dramatically and you will completely lose scanline definition.
