Description: JNEW 6J52P (6Ж52П) ~ (D3a /E810F /7788) USSR TUBES N.O.S. Military Grade6Z52P LOT 16 pcs. Specification 6J52P (6Ж52П) 6Z52P Miniature low noise pentode.Designed to amplify the voltage in wideband amplifiers.The location of the pins RSH8.Durability of at least 1000 hoursMass not more than 15 g.Main technical characteristics of 6J52P:Nominal electrical data:• Tension of heat, V ...... 6.3 ± 0.6• Filament current, mA ...... 330 ± 40• Anode voltage, V ...... 100• Voltage on the second grid, V ...... 150• Resistance in the cathode circuit, Ohm ...... 24• Current in the anode circuit, mA ...... 41 ± 11• Current in the second grid circuit, mA ...... no more than 8• Slope, mA / V ...... 55 ± 10• Input impedance, kΩ ..... 0.7• Equivalent noise resistance, ohm ..... 150• The current of the first grid is inverse, μA ...... not more than 0.2 Maximum permissible electrical quantities:• The highest voltage at the anode, V ....... 250• The highest voltage on the second grid, V ....... 250• Maximum power dissipated at the anode, W ...... 7.5• Maximum power dissipated in the second grid, W ...... 1.2• The greatest current in the cathode circuit, mA ...... 60• The highest voltage cathode heater, V ..... 200• The greatest resistance in the circuit of the first grid, mΩ ...... 0.5 IMPORTANT INFORMATION! BE SURE TO READ BEFORE ORDERING! The valves have areas with smoked glass on the glass cylinder. 6j52p valves are only roughly similar to western valves (D3a /E810F /7788) but are not their full analogs. 6j52p pinout is the same as (D3a /E810F /7788) but some electrical parameters are different. To test 6j52p valves with testers for testing (D3a /E810F /7788) are incorrect. According to my statistics only in about 50% of cases 6j52p valves meet the parameters (D3a /E810F /7788) and can be used to replace western analogs without changing the bias voltage. I do not accept any claims for non-compliance of 6j52p parameters with parameters (D3a /E810F /7788). You buy 6j52p as an original vintage valve made in the USSR with excellent sound and durability, but not as a copy (D3a /E810F /7788). 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!
