Pahom I tested the tda 7000 only with voltage on pin 5+ and pin 16 gnd voltage 4.5 volts and the current it consumes is 90 ma. I'm crying for my money 18.31?. I will look very carefully where to order from.

According to the passport, the TDA 7000 has a consumption of 8 milliamps. And you have 90 milliamps, try to turn off the amplifier, maybe there's a problem with it.

The TDA 7000 circuit is not working. Modifications are needed to make the 7000 circuit compatible with the DCH 85.

Hi dubulumach
In your dch schematic pin 6&7 ic4 should be connect to the groun with capicitor maybe 10 mf
And ext....

Best regard

Finally, does anyone know what material the large circle is made of? Is it iron or plastic????

Hello Zico,
both of them, the big cylinder and the small one are made from the same plastic material, probably ABS or PVC.

Hi Pahom. The dta 7000 I have is defective.

hi Bill 512. now i use pvc pipe.

Hello Dubulumach. How many carats should the gold wire be?? 14K gold, 18K gold, 24K gold?? and what percentage of silver wire should it be 925 silver or 999 silver??? the coil stimulator 2 that is connected and what is its relationship with the circuit? what is the flip flop?

[Zicos]

I have a tda 1083 and a CD 2003. Can it replace the tda 7000???

Hi all members i hope you succeed in your project

hello abdou 2014.,👍

How are you brother

[aft_72005]

The original DCH design works well.
I added a threshold volume to it.
It detects a 10x10cm piece of copper buried 12 years ago from a distance of 3m.

I'm fine abdou. How are you? This year I don't have any time to go hunting 😮*💨 a lot of work this year.

hello aft 72005 . what is the original design of the circuit you are talking about ? does it also have tda7000?
