Description: 6N23P-EV vacuum tube by Reflektor factory. Equivalent to 6H23P-EB, 6922, E88CC, 6N23P 6Н23П (M3624, CV5358, ECC88, E88CC, 6DJ8).Valve is new. Made in (USSR / Soviet / CCCP).Price for 2 pcs. 6N23P-EV specifications and electrical parameters :Filament voltage 6.3 ± 0.6 VHeating current 310 ± 25 mAAnode voltage nominal (constant) 100 VAnode voltage limit (constant) 300 VAnode current of each triode 15 mAThe cathode current limit 20 mALimit cathode current (pulse amplitude) 200 mAGrid voltage (constant) 9 VLimit grid voltage (pulse amplitude) 260 VThe power dissipated by the anode, the maximum 1.8 WThe power dissipated by the grid, the limit of 0.03 WThe voltage between the cathode and the heater limit (constant) -200 VThe steepness of the characteristics of each triode 12.7 mA / VThe gain of each triode is 34 ± 9Input impedance at 200 MHz 500 OhmEquivalent resistance of intra-tube noise 300 OhmResistance in the cathode circuit for automatic bias of 680 OhmsResistance in the grid circuit limit 1 MΩInput capacitance of each triode 3.6 pFOutput capacity of the first triode 2.1 pFOutput capacitance of the second triode 1.9 pFCapacity through passage of each triode 1,5 pFThe capacity of the anode - the cathode of each triode is 0.18 pFThe capacity between the anodes is not more than 0.06 pFCapacity between grids no more than 0,005 pFMaking a glass miniature non-original boxes used to describe the characteristics of the tubes IMPORTANT NOTICE!! You can get differ tubes with other parameters, not like at the photo. Because I have many tubes and can not make photo of each. So, you will get one Matched PAIR with very similar parameters (WITH 1% tolerance), but they must not be the same as at the photo. TESTING PROCESS INFOWe actually test all sold tubes on L3-3 testers (sometimes L1-3).We have more than 10 such devices each ajusted precisely for the specific tasks.When selecting tubes close in parameter, we re-test on the best (carefully calibrated devices.It is theoretically impossible to select tubes with a difference of 0% on any device.From a batch of 100 pieces of any new or vintage number of pairs with a spread of 1-2%, no more than 10.During testing, any tube changes its parameters by 1-2% in any direction over time.This information is based on inspections of over 100,000 tubes over many years.-- Please Note: Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are the buyer's responsibility.
