Description

Miniature type used as horizontal-oscillator and fre- quency-control tube in color and black-and-white tele- vision receivers. Outlines section, 6B; requires minia- ture 9-contact socket. Types 5JW8, 6LX8/LCF802 and 9JW8/PCF802 are identical with type 6JW8/ECF802 9AE except for heater ratings. 6JW8/ 6LX8/ 9JW8/ 5JW8 ECF802 LCF802 PCF802
