Decide how much amplification you want. Right now you have a Q of 6 which is the impedance ratio of the reactance to resistance at resonance. I estimated the reactance ~300Ω /50 =6 , 2pi f L=300 = 1/(2pi f C). If you want a Q of 1 make the ratio of Zc/Rs=1
...that means make the L 6x smaller and the C 6x bigger...if you want Q=1
Not sure what this is for....maybe you want high Q....
Where is your rectifier?...keep in mind that will drop the Q. if unbuffered. use a common collector NPN with load cap followed by PNP CC with load cap for zero offset or an OPA. with diode feedback and charge cap for a peak detector...
