1614

1614 has no equivalent designation confirmed by the archive.

Description

The 1614 is a transmitting beam power amplifier. It has a unipotential cathode and a small-wafer octal 7-pin base.

Construction

The 1614 heater requires 6.3 volts at 0.9 amperes. Its base pin assignments are: pin 1, shell; pin 2, heater; pin 3, plate; pin 4, grid No. 2; pin 5, grid No. 1; pin 7, heater; and pin 8, cathode and grid No. 3. The tube has a maximum overall length of 4-5/16 inches and a maximum diameter of 3-3/4 inches. It can be mounted in any position.

Electrical Characteristics

At a plate current of 72 milliamperes, the 1614 has a transconductance of 6050 micromhos. Direct interelectrode capacitance from grid No. 1 to plate is 0.4 picofarads; input capacitance is 10 picofarads; output capacitance is 12 picofarads. The characteristic curves for type 807 apply to the 1614 within its maximum ratings.

Ratings

For ICAS (intermittent commercial and amateur service) operation, the 1614 has a maximum DC plate voltage of 550 volts, a maximum DC grid No. 2 voltage of 400 volts, and a maximum plate dissipation of 25 watts. Maximum DC plate current is 110 milliamperes, maximum grid No. 2 dissipation is 3.5 watts, and maximum peak heater-cathode voltage is 200 volts.
