6AV5-GA—12AV5-GA 6AV5-GA 17AV5-GA—25AV5-GA I2AV5-GA 17AV5-GA i 25AV5-GA actonte BEAM PENTODE V5-GA TUBES Page | FOR TV HORIZONTAL-DEFLECTION AMPLIFIER APPLICATIONS The 6AVS-GA is a beam pentode designed primarily for use as the hor- BASING DIAGRAM izontal-deflection amplifier in television receivers. The tube exhibits high perveance, high plate current at low plate and screen voltages, and a high 4 © ratio of plate to screen current. Except for heater ratings, the 12AVS5-GA, 17AV5-GA, and 25AV5-GA are B) 6) identical to the 6AV5-GA. In addition, the 12AV5-GA and 17AV5-GA, which feature a controlled heater warm-up characteristic, are especially suited for use in television receivers with series-connected heaters.

The duty cycle of the voltage pulse must not exceed 15 percent of one scanning cycle. § Value given is to be considered as an Absolute Maximum Rating. In this case, the combined effect of supply voltage variation, manufacturing variation including components in the equipment, and adjustment of equipment controls should not cause the rated value to be exceeded. A\\ln stages operating with grid-leak bias, an adequate cathode-bias resistor or other suitable means is required to protect the tube in the absence of excitation. @ Applied for short interval (two seconds maximum) so as not to damage tube. **Triode connection (screen tied to plate) with Eb =Ec2=150 volts and Ecl = —22.5 volts,
