6374

6374 is also designated EY84.

Description

The 6374 is an indirectly heated half wave rectifier primarily intended for operation at high altitudes.

Ratings

The heater is rated at 6.3 volts and draws 1.0 amp. The plate peak inverse voltage is 2,000 volts, the peak plate current is 900 mamps, and the peak heater to cathode voltage is 500 volts. The valve voltage drop is 22 volts at a plate current of 150 mamps.

Construction

The 6374 uses an E9-1 small button noval 9 pin base. The maximum overall length is 3 3/16 inches, the maximum seated height is 2 15/16 inches, and the maximum diameter is 7/8 inch. A top cap, which is skirted and miniature, is connected to the plate. Pin 3 is connected to the cathode, and pins 4 and 5 are connected to the heater.

Operating Characteristics

The Mullard datasheet gives a plate current of 150 mamps at a plate voltage of 500 V r.m.s., and a plate current of 125 mamps at a plate voltage of 625 V r.m.s.

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.
