Pistol like Mineoro

[Morgan]

thanks for the info,

it seems the C4 is hide in the circuit with black resin... (?)

how can I take out this material?

[humhum]

Need to be near 680

Hello.
No need to take out this capacitor.
You can follow the schematics that will atach at next posts.
For the time i attach here the photo of the solder side of pcb.

[Geo]

Cut the tracks at point A and B as at photo (white color)

[Geo]

Conect (solder) a wire as the blue line.....

[Geo]

Now you can try any capacitor at new position of C4

Geo, what is the specification of the coil? What is the inductance, how many turns, Ang wire size..thanks.

[GOLDEN LILLY]

Geo, can you complete the picture..the other half of the pcb solder side is missing...

Sensor (chamber) has n't pcb. It is fixed on a wooden plate.

You don't want nothing.....
Next time that will open a Mineoro i will destroy the input coil to measure the turns

Geo, why is it that in the picture above, point A & B is cut? Where is now the C4 connected?

[Geo]

C4 is connectd via blue line to C3.
C3 is the ((input capacitor)) of receiver
