Higher Pa_max than standard Western EL84: 14 W vs 12 W. This is a genuine rating difference, not just a rebranding.
Screen dissipation: 2.2 W for base 6P14P, 2.0 W for V/EV variants.
Vhk_max is 100 V for base 6P14P vs 200 V for V/EV — critical difference for series-heater or elevated-cathode circuits.
6P14P-EV is the military-grade version: 5000-hour life, -60 to +70 °C ambient, 10 g vibration, 300 g single impact. Standard 6P14P is rated 3000 hours with 2.5 g vibration only.
Internal resistance (ra) is not stated in the Soviet datasheet. The EL84 ra ≈ 38 kΩ (from Philips/Mullard) is applicable as the tubes are electrically equivalent.
No triode connection data in the Soviet datasheet. EL84 triode data (from Mullard/Philips datasheets) is applicable.
