These vintage, 1980s – military specification – General Electric valves are a perfect upgrade,JAN GE5654W 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 JAN 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 3.7 kOhm 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.
