7119

7119 is also designated E182CC. Completed sales put the typical price at $59.00 per tube.

Description

The 7119 is a special quality double triode with separate cathode connections, designed for use in electronic computer circuits. It has coated, unipotential cathodes and is not intended for circuits critical as to hum, microphony and noise.

Construction

The 7119 has an E 9-1 base, a T6 1/2 bulb, and outline 6-3. Its basing designation is 9н. It may be mounted in any position. The heater can be arranged in series with a voltage of 12.6 volts and a current of 320 mA, or in parallel with a voltage of 6.3 volts and a current of 640 ± 35 mA. The maximum bulb temperature is 160 degrees centigrade.

Pinout

For triode no. 1, pins 1, 2, 3, 4, 5, 6, and 6 are Plate, Grid, Cathode, Heater, Heater, Cathode, and Cathode respectively; pin 7 is the grid of triode no. 1. Pin 8 is the heater mid tap. Pin 9 is the plate of triode no. 1.

Ratings

The 7119 has a maximum plate voltage of 300 volts, a maximum plate dissipation of 4.5 watts per section, a maximum negative grid voltage of 100 volts, a maximum peak negative grid voltage of 200 volts (time max. 10 µsec at a duty cycle of 1 %), a maximum positive grid voltage of 1 volt, a maximum peak positive grid voltage of 30 volts (time max. 10 µsec at a duty cycle of 1 %), a maximum grid current of 8 mA, a maximum peak grid current of 200 mA (pulse time max. 10 µsec at a duty cycle of 1 %), a maximum peak cathode current of 200 mA (pulse time max. 10 µsec at a duty cycle of 1 %), a maximum cathode current of 60 mA, a maximum grid circuit resistance of 1 megohm with automatic bias, a maximum grid circuit resistance of 0.5 megohm with fixed bias, and a maximum peak heater-to-cathode voltage of 200 volts (pulse time max. 10 µsec at a duty cycle of 1 %).

Characteristics

The amplification factor is 24, and the typical transconductance is 15000 micromhos. At a plate voltage of 120 volts and a negative grid voltage of -2 volts, the typical plate current is 36 mA; at a plate voltage of 150 volts and a negative grid voltage of -14 volts, the typical plate current is 0.2 mA. At a plate voltage of 120 volts and a cathode resistor of 55 ohms, the transconductance is 11200 micromhos. At a plate voltage of 120 volts, a negative grid voltage of -2 volts, and a grid series resistor of 0.1 megohm, the negative grid current is 0.2 µamps. With a cathode to heater voltage of 200 volts (cathode positive) and a series resistor of 1 megohm, the cathode to heater leakage current is 15 µamps.

Capacitances

For triode no. 1, the direct interelectrode capacitance between plate and cathode and heater is 1.1 pF, between grid and cathode and heater is 5.8 pF, between plate and grid is 3.9 pF, and between cathode and heater is 3.7 pF. For triode no. 2, the direct interelectrode capacitance between plate and cathode and heater is 1.0 pF, between grid and cathode and heater is 5.8 pF, between plate and grid is 4.0 pF, and between cathode and heater is 3.7 pF. The plate-to-plate capacitance between the triode sections is 0.6 pF, and the grid-to-grid capacitance between the triode sections is 0.15 pF.

Equivalence is asserted only where the archive's own literature states it directly, in at least 40 separate documents. Tubes that merely substitute in some circuits are not listed here.
