6N3

6N3 is also designated EY82. Completed sales put the typical price at $13.34 per tube.

The 6N3 is a high-vacuum single-anode rectifying tube with a coated unipotential cathode and indirect heating via an oxide cathode. It is an all-glass miniature tube with a nine-pin base (E9-1) and a 6.3-volt heater drawing 0.9 ampere. The tube weighs a maximum of 16 grams.

Ratings

Maximum ratings for the 6N3 include a peak inverse plate voltage of 850 volts, an inverse voltage of 700 volts, a DC output current of 360 milliamperes, a peak plate current of 1100 milliamperes, and a peak rectified current of 1100 milliamperes. The rectified current is rated at 180 milliamperes maximum. Heater-cathode voltage limits are specified as 450 volts maximum (with a separate DC component rating of 220 volts maximum and an AC component rating of 20 volts maximum) and 550 volts maximum in another rating. The maximum filter input capacitor is 60 microfarads for a single tube, or 100 microfarads for two parallel-connected tubes.

Applications

The 6N3 is a single-ended vacuum rectifier suitable for use in receivers and other electronic devices. It operates as a full-wave rectifier when used in pairs.

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.
