. DUPLEX-DIODE TRIODE iesr Etta” FOR DETECTOR AND AF-DRIVER APPLICATIONS IN TUBES AUTOMOBILE RECEIVERS == DESCRIPTION AND RATING =" The 12FM6 is a miniature, duplex-diode triode for use as a combined de- BASING DIAGRAM tector, AVC rectifier, and transistor driver. The tube is specially designed to operate with its plate voltage supplied directly from a 12-volt storage battery. GENERAL ELECTRICAL Cathode—Coated Unipotential @) Direct Interelectrode Capacitancest 1 MECHANICAL Mounting Position—Any Envelope—T-5¥2, Glass Base—E7-1, Miniature Button 7-Pin TERMINAL CONNECTIONS] MAXIMUM RATINGS Pin 1—Triode Grid DESIGN-CENTER VALUES Pin 2—Cathode an Pin 4—Heater Heater-Cathode Voltage Pin 6—Diode Number 1 Plate Design-Center ratings are limiting values of operating and environmental con- ditions applicable to a bogey tube of a specified type as defined by its published PHYSICAL DIMENSIONS data, and should not be exceeded under normal conditions. These values are chosen by the tube manufacturer to provide acceptable service- ~ z ability of the tube in average applications, taking responsibility for normal changes MAX. in operating conditions due to rated supply-voltage variation, equipment component variation, equipment control adjustment, load variation, signal variation, environ mental conditions, and variations in the characteristics of all tubes. The equipment manufacturer should design so that initially no design-center value ir for the intended service is exceeded with a bogey tube in equipment operating " wax. at the stated normal supply-voltage. 25 \\ i z ‘The tubes ond orrangements disclored herein may be covered by patents of General Electric Company or others, Nelther 7 the disclosure of ony information herein nor the sole of tubes by General Electric Company conveys any license under potent claims covering combinations of tubes with other devices or elements. In the absence of an express writlen ogres. tment to the contrary, General Electric Company assumes no liability for patent Infringement arising out of any vse of the tubes with other devices or elements by ony purchaser of tubes or others. oy | GENERAL @@ ELECTRIC am EIA 5-2

These extreme variations in heater voltage may be tolerated for short periods; however, operation at or near these absolute limits in heater voltage necessarily involves sacrifice in performance at low heater voltage and in life expectancy at high heater voltage. Equipment reliability can be significantly increased with improved supply-voltage regulation. { Without external shield.
