Russian economical directly heated miniature pentode intended for mobile equipment, oxide-coated filament 1.25 V 11 mA, flexible leads. Manufacturer-derived summary lists anode voltage 45 V, screen 45 V, grid bias -2 V, transconductance 0.4 mA/V, nominal anode current stated as 0.007 A and anode power 0.05 W, with microphonic noise 100 mV. Printed current/power combination is inconsistent at face value and cannot establish dissipation maximum; 45 V ratings are unspecified as maximum versus operating points. Existing gm retained and maximum fields left NULL.
