Description
Miniature type used in color and black-and-white tele- vision-receiver applications. The triode unit is used as 9HX a sync-separator, sync-amplifier, keyed-age, or noise- suppressor tube. The pentode unit is used as a video-output tube. Outlines section, 6E; requires miniature 9-contact socket. Type 10DX8/LCL84 is identical with type 6DX8/ECL84 except for heater ratings. 6DX8/ECL84 10DX8/LCL84
