Mike,
   I have an on-line calculator for pi & pi-L at this link
http://www.pinebeetle.net/amplifier_main.html . These calculations are based
on the formulas from ARRL handbook.
Regards,
Larry N5BIP


Meanwhile back at the ranch, I 
looked up the formulas for calculating the values in a pi-network in the 
ARRL Handbook, and put them into a Microsoft Excel spreadsheet. 
Interestingly, when I did the calculations for my operating conditions, and 
those in the schematic, they were far apart as far as values are concerned; 
thus the reason for the inquiry here on the reflector. I will probably go 
with the values that provide the correct match for the operating conditions 
in my amp.  Thanks for the response.
