Respected ZUM. You included the instrument without the spool? For me completely is silent. How the circuit works for you after inclusion (the sound is present at dynamics?)?
Make please a photo of the device (from above and from below) in high quality and send to me [email protected], or place in this section. In advance I thank.

PULSE IB DICR

HI EVERY THERE CAN ANY ONE GIVE ME INF- ABOUT COIL ,HOW CAN WOUND THTIS COIL AND WHAT LINE NEAR THE COIL IN DESIGN MEAN

You have started to gather the instrument? What turns out? I have gathered, but it does not publish any sounds. While the spool did not do, wished to check up working capacity of the electronic block in the beginning. And respected Leto, Ivconic, Geto has made this instrument for a long time already and it is uninteresting to answer our questions.

SMITY ask leto he built this detector from his own PCB

CAN I USE TL072 INSTEAD CA3140 AND NE5534




TL072 yes,
they are not pin compatible but should work electrically ok , performance may not be the same, but should work.

It is possible to see the working instrument (give a photo of the ready card)? On printed circuit cards that tip122 turned bc517 not correctly costs, c7 it is overwound. Who can нибудь give the normal instruction on assemblage of this instrument? And that was laid out by the subquality work rejected and be silent!!! This big disrespect for all present at a forum!!! I have gathered it (but did not connect the coil), and he is silent. Give a complete manual...

How to check up on working capacity the block without the spool? For English excuse, it not I, it "Promt translate". All I thank.
