You maybe use LM324 to preamp receive signals and use LM3914 to show signal value by LEDs, yes?
please tell us about your device performance...
I am waiting for your answer...

Hi.
Sorry but i can't give the schematics.
Electrostatic detector is a simple RF ampl and after 4 stages i demodulate the signal. I amplifier it yet and i send it to a beep generator (one 555 and a buzer)
At the MFD i use the LM3915 as indicator and a buzer for beeps.
About performance.... i am yet under test. I take some beeps but i can't pinpoint the object.
Regards
