GP-3 (GP3, ГП-3) is a high-voltage regulating tetrode for operation in electronic high-voltage voltage stabilizers.
Main technical parameters of GP-3:
  • Un = 6.3V; Uc2 = 80V; Uа = 1.2 kV; Ia = 5 mA;
  • Filament current 1.5 ± 0.15 A
  • 2nd grid current no more than 0.2 mA
  • 1st grid reverse current no more than 3 μA
  • The voltage of the 1st grid at the operating point is negative 5.5 ± 1.5V
  • The blocking voltage of the 1st grid is negative (at Uc2 = 100 V, Ia = 0.2 mA) no more than 18 V
  • Slope characteristics 2.65 ± 0.55 mA / V
  • Gain not less than 2500
  • Interelectrode capacitances, pF:
     - grid - cathode no more than 23
