Russian 10J3L (10Zh3L transliteration) communications pentode in a glass envelope with an external metal shield and loctal base, indirectly heated oxide cathode, intended for equipment with series-connected heater chains. Nominal heater 10 V 93 mA; manufacturer maximum anode dissipation 2 W, screen dissipation 0.7 W and screen voltage 225 V. Published maximum anode current 11 mA must not be confused with a universal total cathode-current rating. Typical test points include anode 150 V and screen 75 V; source states guaranteed service life 1000 hours. Voltage ratings at switch-on are distinct from continuous operating ratings.
