Dear Daniele, LF Group,

...>It looks
like something I could try to build, even without rebuilding the loop.
Yes, the component values are not very critical - your existing loop should have near enough the right inductance to work fine in this circuit. The area of my loop is slightly larger, so would give slightly more input signal, but in practice the preamp noise is always 10dB or more below the band noise in the prototype, so this should not matter. 

Cheers, Jim Moritz
