7-Pin 5654W Vacuum Tubes, Fully-Tested Vacuum Tube, Perfect Matched Pairing T...

Description: Feature： These vintage, 1980s - military specification - The valves are a perfect upgrade, 5654W Vacuum Tubes is a great upgrade for Little Dot and Little Bear amps! This tube is a direct replacement for 7-Pin 6J1 / 6J1P / 6J1P-EB / 6Zh1P-EV / 6AK5 / 6AK5W / EF95 tubes. 5654W Vacuum Tubes is very high quality and will last for a long time. We subject 5654W to multiple test cycles and plate voltages to determine stability. In addition to Ip, Gm, leakage/gas, noise and life testing, the matched Vacuum Tubes undergo a final audio sound check to make certain they are indeed audio quality, Vacuum Tubes that show the slightest abnormality are rejected. Technical characteristics and electrical parameters of the 5654W tubes : Filament voltage 6.3 ± 0.6 V Filament current 170 ± 15 mA Anode voltage rated (constant) 120 V Anode voltage limit (constant) 200 V Anode current 7.35 ± 2.35 mA Cathode current limit 20 mA The reverse current of the grid of the first is not more than 0.1 μA The grid voltage is the second rated (constant) 120 V Grid voltage second limiting (constant) 150 V Power dissipated by the anode, maximum 1.8 W The power dissipated by the second grid, the limit of 0.55 W Voltage between cathode and heater limit (constant) 120 V Slope 5.15 ± 1.25 mA / V Cutoff voltage of the anode current (at anode current of not more than 5 μA) no more than -15 V The cutoff voltage of the electronic current of the grid is the first -1.5 V Internal resistance 0.1-1.1 MΩ Equivalent resistance of intra-tube noise no more than 3.7K Ohm Input impedance at a frequency of 60 MHz 12-25 kOhm Resistance in the cathode circuit for 200 bias auto bias The resistance in the first circuit is the limit 1 MΩ Input Capacitance 3.5-4.7 pF Output Capacitance 1.9-2.8 pF Capacitance through passage no more than 0,035 pF The capacity of the cathode-heater is not more than 4.6 pF Miniature glass. IMPORTANT REMINDER: AMPLIFIER DAMAGE CAN OCCUR IF YOU Plug and Play, 5654W For used to directly replace 7-Pin 6J1 / 6Ж1 / 6J1P / 6J1P-EB / 6Zh1P-EV / 6AK5 / 6AK5W and EF95 tubes. It can also replace 6J2/6J3/6J4/6J5 and ordinary 5654. It can used for WE-403A/403B/EF95 Matched Vacuum Tubes replacement.
