The greater the damping resistance of the coil, the greater the resistance the or reduce? Who can tell me, thank you

Yes, I have KT315 designed board, didn't buy from him but I Made it using his design.

ok thank you

Now the detector is working, there was just a stupid mistake- one IC wasn't installed properly.

Hello! I made Delta Pulse detector(I used KT315 designed board), made test coil(12 cm diameter and 36 turns of 0.4 mm wire). I got constant sound from speaker, but no reply to metal objects, when i connect oscilloscope to the testpoint T1 in schematic(output of the preamp), I can see there reaction to metal objects. I also checked T3, T4 and T5 with oscilloscope, these were ok. What should I get at T6 and T7 and what should I check?

Now the detector is working, there was just a stupid mistake- one IC wasn't installed properly.

George, those chineses crap overloaded my email box by bare spam requests to give them 'deeper detector on gold on 3 meters depth'.
so let me overload those bad guys by something they are served up too. they always only ask but never give useful info in the exchange.
i got 1-3 messages everyday!

It is best to ignore all such requests or tell them to post their questions in the forum. Otherwise the questions will be endless.

on a spot R37 R41 you have to see a level slight low than zero with some low freq noise.
then bring a metal and you have to see encrease of the level above zero volt.

No, but it was made using your files.
