This is a Pi tank calculator, useful for impedance transformation in valve amplifiers. The formulas used are taken from EIMAC's "Care and Feeding of Power Grid Tubes".

Enter resonant load impedance (RL) in ohm:

Enter antenna impedance (RA) in ohm:

Enter desired loaded Q:

Enter frequency in MHz:

The C1 capacitor in nF is: The C2 capacitor in nF is:

The L inductor in uH is:
