15CW5

15CW5 is also designated PL84.

The 15CW5 is an audio-frequency output pentode in 9-pin miniature construction, as identified in the Tung-Sol datasheet. It is intended for use in combined phase inverter and push-pull applications.

Ratings

The Tung-Sol datasheet specifies a heater voltage of 15 volts at a current of 300 mA, with a heater supply limit of 300 ±20 mA. Maximum ratings include a plate voltage of 250 volts, a plate voltage without plate current of 550 volts, and a plate dissipation of 12 watts. The maximum grid #2 voltage is 200 volts, with a maximum grid #2 voltage without current of 550 volts. Grid #2 dissipation is limited to 1.75 watts, with a peak grid #2 dissipation of 6 watts. Maximum cathode current is 100 mA. The maximum grid #1 circuit resistance with automatic bias is 1 megohm. The maximum voltage between heater and cathode is 200 volts, and the maximum peak voltage between heater and cathode (cathode positive with respect to heater) is 300 volts, with a circuit resistance between cathode and heater of 20,000 ohms.

Capacitances

The datasheet gives typical grid #1 to all other elements except plate capacitance as 11.8 pF, typical plate to all other elements except grid #1 capacitance as 6.0 pF, maximum plate to grid #1 capacitance as 0.6 pF, and maximum grid #1 to heater capacitance as 0.25 pF.

The Tung-Sol datasheet was published by Tung-Sol Electric Inc., Electron Tube Division, Bloomfield, New Jersey, U.S.A., on December 1, 1961.

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.
