Classification- Aubergine-type bulb of glass, a white ceramic base with four-prong bayonet golden pins, oxide coated filamentary, mesh plate or carbon plate triode.

Application -Audio frequency amplifier where power outputs of approximately 4.5watts or less is required at relatively low plate voltages.

Dimensions -Dimensions, outline diagrams of the tube and bases, and the arrangement of electrode connections to the base terminals are shown in Figures 1 and 2.

Nominal operating conditions and parameters
Filament voltage* .............................4V
Nominal filament current ................1A
Plate voltage ......................................300V
Grid voltage** ....................................-45V
Plate current ......................................50mA
Impedance ........................................830 ohm
Amplification factor ..........................5.0
Mutual Conductance .....................6.0mA/V
Grid current ...........................0.05 μ A

*Alternating-current filament supply or Direct-current filament supply.
**Alternating-current filament supply is used. The grid and plate returns should be connected to a center tap on the secondary of the filament transformer.
Direct-current filament supply is used. The grid and platter returns are connected to the negative end of the filament.

Characteristics-Average characteristics
Figure 3. shown typical curves of plate currents of grid voltage for several values of plate voltages. It is alternating-current filament supply.
