help .. deepers x5 schematic

Deepers 8 AT has the circuit AutoTune incorporated

Deepers X5

I dont have time for internet in my country, sorry, the deepers schematics work fine, my deepers x5 is an updated home made deepers 8. I had modified the 8 to X5 acording these schematic posted in the forum by me. My coil is a 12 wires computer network cable. It have 8 internal wires but it need 12 for 2.5 ohms. In a 8 shape and after in a heliptical 53x25 cm, very powerfull believe me. I get in ground 70 cm aprox with a pop can aluminiun, strong audio redponse. Only I dont use discri part, no amp op and no potentiometer or discri led.

thanks Is illustration in the picture is true

in schematic deepers 10 dd
LM336
How is it installed.. In the schematic and on the board, only two pin are installed...Is this correct?

Please explain how to install it

Hi,

the LM336 in the ciruit is used only as a "fix" 2.5V precision zener diode. Looking at the partial PCB layout from the image you can expect more funny errors in the PCB. The routing is everything else than professionally made. The the parcial posted schematic also does not match the PCB layout as you can see in the case of the LM336. My advice is take the Deepers schematic as a "design idea" only and make your own schematic with a propper PCB layout design program and cross check all circuit parts with the official manufacturers data sheet and/or application notes.

Thank you... I actually did that and re-designed it again... and the device worked fine for me except for the part related to this component 336 where a variable resistor is connected to it and it does not work without installing this component correctly, so I came here to ask
