6V6
6V6 has no equivalent designation confirmed by the archive. Completed sales put the typical price at $21.50 per tube.
Description
The 6V6 is a beam power tube of metal construction. It is used as an output amplifier in automobile, battery-operated, and other receivers in which reduced plate-current drain is desirable.
Heater and Ratings
The 6V6 has a heater voltage of 6.3 volts and a heater current of 0.45 ampere, with a heater warm-up time of 11 seconds. Its peak heater-cathode voltage rating is ±200 volts, and its average heater-cathode voltage rating is 100 volts. The maximum grid-No.1 circuit resistance for cathode-bias operation is 2.2 megohms.
Related Types
The 6V6GTA is a variant with the same heater voltage and current (6.3 volts, 0.45 ampere) and the same heater warm-up time of 11 seconds. Its peak heater-cathode voltage rating is ±200 volts, and its average heater-cathode voltage rating is 100 volts. The 6V6GTA is used in the audio output stage of radio and television receivers. Type 12V6GT is identical with type 6V6GTA except for heater ratings, having a heater voltage of 12.6 volts and a heater current of 0.225 ampere.
