Vacuum Tube - 6293, Beam Power Amplifier

New-Old-Stock (NOS) tube.

The 6293 is a small, sturdy, beam power amplifier tube intended for pulse modulator service in both fixed and mobile equipment. It can deliver a peak plate current of 3 amperes during a pulse length of 30 microseconds under conditions with duty factor or 0.003 and plate-supply voltage of 2000 volts; or a peak plate current of 1.4 amperes during a pulse length of 200 microseconds under conditions with duty factor or 0.02 and plate-supply voltage of 3500 volts.

Small in size for its power-output capability, the 6293 has a rugged button-stem construction with short internal leads, a T-12 bulb, triple base-pin connections for grid No. 3 and cathode (both joined to internal shield inside the tube), and an octal base with short metal sleeve having its own base-pin terminal. The plate lead is brought out of the bulb to a cap opposite the base.
