Description: LOT 4 pcs. tubesGU-32 GU32 ГУ-32 a-g 832 vacuum double beam tetrode tube NEW - N.O.S. USSR Military Grade! OTK Mark! = With Original FACTORY BOX Boxes may be torn and also slightly different in printing (colors and font size) Tetrod GU-32 is designed to generate and amplify the power of high frequency oscillations. It is used in transmitting devices. Cathode oxide indirect heating. Works in any position. Produced in a glass design. Service life is not less than 500 hours. The leads of the electrodes are pins. Pin 7.Double beam tetrode for use as a generator and amplifier of high frequency fluctuations in the meter wavelength range.Design - glass, wedge base (РШ3).Cooling - natural.Weight 100 g.+ Box 15 grwhen UN=6.3 V, Ua=0.4 kV, Uс2= 250, Ia= 19 mAFilament current in parallel connection of the heaters of 1.6 ± 0.16 AFilament current in series connection of the heaters of 0.8 ± 0.08 AThe anode current of one of the tetrode 30 ± 12(31,5 ± 13,5 for GU-32) mACurrent 2nd grid for a single tetrode £ 5,5 mACurrent 1st grid reverse £ 2 µaThe vibrational power(if Іс2=11 mA I a + I"a=90 mA, frequency 100 - 200 MHz) 3 14 WThe decrease in oscillatory power (at h=11.3 V) £ 20 %Interelectrode capacitance, pF:input 7,8 ± 1,6the output of 3,8 ± 1,2gate £ 0,5The durability of the medium 3 1000 (500 for GU-32) hThe vibrational power(if Іс2=11 mA I a + I"a=90 mA, at a frequency of 90 MHz) 3 14 WCriteria of durability:oscillatory power 3 11 Wthe decrease in oscillatory power (at h=11.3 V) 20 %Limit operating dataFilament voltage if series connection of heaters 11,3 - 13,9 InFilament voltage with parallel connection of the heaters of 5.65 - 6.95 perThe voltage of the anode 500 InVoltage 2nd grid 250 InThe voltage between cathode and heater 100 InThe cathode current 100 mAThe power dissipated by the anode 15 wattsThe power dissipation of the 2nd mesh 5 WThe temperature of the cylinder 115 WithThe range of operating ambient temperatures from -60 to +70 C IMPORTANT INFORMATION! BE SURE TO READ BEFORE ORDERING! In the title of the lot is the name of the vintage Soviet tube and after the symbol ~ the name of the Western analog. Be careful! Soviet tubes are only approximate analogs of Western tubes and match pinout, but are not exact copies of Western tubes. Testing Soviet tubes with Western-made tube testers can sometimes show unreliable results. Programs (Cards) designed for testing Western tubes can sometimes show unreliable results and erroneously show that the tube is not good enough. But these are unreliable results and should be disregarded. The volt-ampere characteristics of Soviet tubes are different from their Western analogs!Use for testing exclusively testers with programs for testing Soviet tubes. If you would like to get the datasheet for the Soviet tubes in this lot, please send me a message before you place your order and I will send you a JPG datasheet for the Soviet tube. Also, do not test vintage tubes with modern digital pulse powered tube testers. Use only testers with a classic power supply. For reliable measurement results, warm up each tube for at least 5 minutes prior to measurement. I do not accept any claims on the quality of tubes if you test purchased Soviet tubes of this lot on testers with programs (modes) of testing Western tubes or test tubes on digital testers with pulse power supply. Dear customer, you can combine shipping buying more than one lot.If You need more than one lot, or another quantity - please contact. Also please check other available items. Thanks in advance!
