It can be reduced by choosing very pure materials for the cathode nickel, and running the tube at an optimized ( generally low ) anode current.

Another option is to add overcurrent protection in the external circuit, so that when the measured anode current exceeds a safe limit, the high voltage is reduced.

Amplitude distortion in a class A triode stage can be small if care is taken to prevent the anode current from becoming too small and ensuring that grid current does not flow at any point.
15.
The 2J42 Magnetron, with a power output of some 7 kilowatts, is rated for anode current of 4.5 amps ( pulse peak ) at anode voltage of 5, 500 volts.
16.
The anode current is set by the value of the grid voltage relative to the cathode and this voltage is now dependent upon the value of the resistance selected for the cathode branch of the circuit.
17.
The input signal is able to perturb ( change ) the potential of the grid, this in turn will change the anode plate so hence on many designs the anode current is named the plate current.
18.
In 1942, the 958A with tightened emission specs was introduced after it turned out that 958s with excessively high emission kept working after the filament power was turned off, the filament still sufficiently heating on the anode current alone.
19.
Although Edison was aware of the unidirectional property of current flow between the filament and the anode, his interest ( and patent ) concentrated on the sensitivity of the anode current to the current through the filament ( and thus filament temperature ).
20.
The design is today known as the beam tetrode but historically was also known as a kinkless tetrode, since it is a four-electrode device without the negative resistance kink in the anode current vs anode voltage characteristic curves of a true tetrode.
