I am looking to find the resonant frequency of the amplified tuner circuit below
The equation I have attempted to use is the f = 1/2*pi*√LC
With the values for the inductance capacitance being 22pF and 47mH as I believe this is the tuner part of the circuit?
The value I get by inserting these values is 156.5kHz.
But from doing a practical experiment using this circuit I know the resonant frequency is somewhere between 65kHz and 75kHz. Can faulty equipment be to blame for such a difference in values? Or is there a specific equation to be used for amplified tuner circuits?
Thanks for any help!
