[Amps] PI Calculation using G3SEK Excel Spreadsheet

[Bill Smith <ko4nrbs@yahoo.com>]

Are these values correct (in ??) for two 3-400Z tubes at 2500vdc and 800ma 
Plate Current?
There is so much information there I get lost.

Input   Supply voltage  E       2500    V

Input   Max DC anode current    Ia      0.8

Input   K factor        K 1.6   
                        
Input   RF power output W       1500    W ??

Info    Estimated RL based on E, I and K                1953    ohms??
                                
Input   Efficiency      e       56      %??

Info    Estimated RL based on E, W, e and K             1458    ohms??
                                
Input   Enter your choice of load resistance to be used for the calculations.   
RL      1900    ohms??
                                
Input   2: Antenna load resistance      R2      50      ohms??
Input   3: Operating frequency  F       7.2     MHz
Input   4: Overall network Q    Q0      12      
                                
        5: Strays compensation                  
Input   Output capacitance of tube(s)   Cag  10 pF??

Input   Strays local to tube    Cs1     5       pF

        Cout = Cag + Cs1        Cout    15      
                                

                                
Info    Total effective parallel capacitance of tube, strays, RFC etc   Cp      
25.0    pF??
