      interesting, i am using an LF351 as an inverting op amp, with a one ohm
      input resister and a 10k feed back with a .001 uf in
      parallel..................the loop is connected between ground and the
      one ohm resister, with a .1uf cap across the loop (am broadcast filter).
      the output of the LF351 is about 5 volts pp, so i need no other
      amplification, so i have a 5 K pot as a variable gain, and a passive band
      pass filter connecting the preamp with the dan.

      simple
