When using the TUBEDATA.EXE File Utility you will be queried
for the device parameters in the following order.
The 3CX5000A7 is used as an Example.
Name = 3CX5000 (Name of File, use DOS conventions
.TUB extension automatically added)
VB Max = 6500 (Maximum Plate Voltage Rating)
VB Low = 400 (From Grounded Grid Constant Current
Characteristics curves.
VB High = 1100 (From Grounded Grid Constant Current
Characteristics curves. ~ 2 to 3 * VB Low)
Gain = 200 (Tube Amplification Factor)
Cin = 56.5 (Grid-Cath Capacitance in pF)
Cout = 34.0 (Grid-Plate Capacitance in pF)
PDiss = 5000 (Max Plate Dissipation of Device)
GDiss = 50 (Max Grid Dissipation of Device)
Cooling = Forced Air (Enter description of required Cooling Method)
"The following requires the user to use interpolation of the curves
to select the Grid Voltage & Grid current per IB. Determine which
IB (Peak Plate Current) curves are to be used. 8 IB's are required,
as are the corresponding EG, IG inputs per VB Low, VB High.
Enter Grid Voltages as a positive value."
Input IB: 2,3,4,5,6,7,8,9
Input EG @ VB Low: 50,67.5,92.5,110,127,145,166,178
Input EG @ VB High: 42,60,82.5,95,110,125,141,155
Input IG @ VB Low: .088,.163,.355,.474,.744,.956,1.218,1.75
Input IG @ VB High: 0,.005,.01,.02,.065,.113,.167,.232
"Once the last input is done a file can be generated in the
correct format for the TRIODE.EXE program."
