Russian 1P22BV high-durability directly heated miniature pentode for high-frequency oscillation and amplification, 1.2 V 125 mA filament (110–140 mA range), flexible wire leads. Typical anode 90 V, screen 90 V, control grid -4.5 V, transconductance 3 mA/V (2.3–3.7 range) and printed anode power 2.5 W. Manufacturer-derived summary specifies microphonic noise 600 mV nominal (400–800 mV range), distinguishing this designation. Voltage and power figures are not expressly identified as maximum ratings, so promoted maxima left blank.
