The GI-13BM (GI-130M) triode is used in selfexcited oscillator circuits with no external feedback, operating in continuous-wave or pulsed mode with anode modulation in the decimetric wavelength range.
The triode is available in two variants differing in the type of cooling: the GI-13BM with a heat sink for forced air cooling and the GI-130M with no heat sink for other systems of cooling.
Cathode: indirectly heated, oxide-coated.
Cooling: forced air.
Height: 88.5 mm with heat sink, 63.7 mm with no heat sink.
Diameter: 46 mm with heat sink, 26.3 mm with no heat sink.
Mass: 120 g with heat sink, 60 g with no heat sink.
KP - cathode and heater; P - heater; C - grid; A - anode
