Bill,
I am currently doing the same thing with a Pi-L tank. I use a carbon
resistor of the proper value to simulate the anode impedance. I use a
capacitance meter to set the proper values of capacitance for Ct & Cload and
drive the tank output with my MFJ SWR Antenna Analyzer, using the frequency
meter and SWR bridge to determine the resonant frequency of the tank. Since
capacitance vaues can be determined very accurately, it is best to set them
and then adjust the inductors to bring them into comformance.
Good luck.
Dave, WT8R
