Description

Duodecar types used as a combined limiter, discrimi- nator, and audio power-output tube in FM radio and television receivers. Outlines section, 8C; require duodecar 12-contact socket. Types 10Z10, and 13Z10/ 13J10 are identical with type 6Z10/6J10 except for 12BT heater ratings. 6Z10/6J10 10Z10 13Z10/13J10 Heater Voltage (ac/dc) 6.
