Esteban please make me zahori coil coupling for help. This coil is made in what form?
Esteban zahori you can trace metals in the basement does?
With respect
This is other coupling capacitor plate (inside ceramic) and spiral coil. One lead of capacitor is connected to ground for control interference. The other to CA3130.

Hello good friend who tells me again that a thing can use the IC CA 3140 in place of the CA3130 IC???
Thank you appreciate their improvements.
Using the CA3140 instead of CA3140 should be no problem, maybe it is a bit less sensitive.
I think can be replaced by 3140 or TL071 or TL081. Also can be redesigned for dual op amps based in TL082. This dual op amp is equal to 2 op amps. So, you need an only chip.
