Common types available on eBay and other online resellers from Russia, Bulgaria and Ukraine.All direct heated filament/cathode and about 8mm to 10mm glass with Anode on top wire.For reliable longest life operate at less than 1.4V and more than 0.9V filament (not direct from Zinc, Alkaline, NiMH cells) and operate at less than maximum currents and voltages.In English transliteration the Ж Cyrillic Character may be written j, sh, zh, SH or ZH Typical Filament mA currents for 1.35V. VG2 is minimum at quoted HT and HT is “typical” not maximumRL1 = Approx min Anode load for max power (K Ohms at listed HT). RL2 = Approx max Anode Load for max gain, small signal (K Ohms at listed HT)gm listed is below max listed but above minimum listed for 0.95V filament. It varies with HT and filament current more than 2:1Pa is maximum Power, likely at higher HT than listed.

Mixer or AGC (not Osc/Mixer) 1j29bCalculations suggested 8.2 Ohm resistors in each of its pair of filaments interconnected at “f+”. I didn’t have them so tried 1% 10 Ohms. These had 26.8mV and 27.6mV each, thus about 54mA total current. Filament voltage about 1.07 with a 1.35V NiMH. Graphs in “Triode” mode (g3 = 0V,g2 connected to anode). f+ is 1.35, and f- is +0.27V, LT- and HT- is common as 0V, thus g1 = 0V is actually between -0.27 and -0.7 negative.The “official” Pentode curves show 5.5mA from 25V to 70V for g1 = 0V and filament = 1.2V, so 5mA seems ok. Total currents of all electrodes (cathode current) must not exceed 8mA, Since the cathode is the filament, any excessive currents heat the filament. So perhaps running the higher power valve 0.05V lower than lower power ones is OK. (10 Ohms is probably better than 8.2 Ohms). A 10K Ohm load for Anode seems about right for 45V HT Class A. I will test later.The datasheet indicates that 150V is absolute Maximum Va and 120V absolute Maximum g2. 90V g2 seems to be an acceptable HT. The valve is suitable for 45V HT and can be used in some fashion at 9V or 18V.The 1j29b-r (1Ж29Бp) sample used 52mA and the two filaments very closely matched. A bias of about -1V is needed for 45V HT. A -5V supply with 390 k to g1 and 100k from g1 to 0V gave -0.9V and resulted in Va =22V, Ia= 2.25mA, Vg2 = 42V, Ig2 = 0.23mA with 44.5V HT, 15K g2 to HT and 10K Anode to HT.The Russian datasheets all have Pentode curves and all ratings. For true “Pentode” style operation at least 25V HT/G2 volts is needed.Sources many sellers in Russia, Bulgaria and Ukraine on ebay. “Decoding” the datasheetsVoltage Filament Voltage Anode Current Anode Voltage G2 (grid second) Current G2анод = Anode экран = Screen or Shield катод = Cathode накала = filament минус = Minus / Negative плюс = Plus / Positive ток = Current напряжение = Voltage первый = first второй = second треть = thirdРуководство по применению стержневых радиолампСтержневые радиолампы, где управление электронным потоком идет не с помощью сеток, преграждающих электронный поток, как у обычных радиоламп, а с помощью стержневых электростатических линз, изменяющих интенсивность и фокусировку электронного потока, — это гениальная советская разработка. Они были созданы в середине 50-х годов для военной и космической аппаратуры. Массовое распространение получили в начале 60-х годов. У них огромная надежность, ударо- и вибропрочность, стабильность параметров, долговечность, сравнимая с транзисторами, а «ламповая» радиационная стойкость делает их идеальными усилительными устройствами для работы в условиях радиационного и космического излучения.Application guide rod tubesRod radio tubes, where the control electron flow is not using grids, blocks the electron flow, as in conventional tubes, and rods using electrostatic lenses that change the intensity and focus the electron beam – this is a brilliant Soviet development. They were created in the mid-50s for military and space equipment. The mass distribution obtained in the early 60s. They have great reliability, shock and vibration, stability parameters, durability, comparable to the transistor, and the “lamp” radiation resistance makes them ideal amplifying device to operate in conditions of radiation and cosmic rays.
