GB/T 3789.20-1991 Measurements of the electrical properties of transmitting tubes--Measuring methods of grid No1 current cut-off voltage (English Version)
This standard specifies the test method for the cut-off voltage of the first grid current of the emitter tube. This standard is applicable to the space charge controlled oscillation, modulation, adjustment and test of the cut-off voltage of the first grid current of the power amplifier tube with the anode dissipation power above 25W.
