Pulse Star II (first analog version)

[Mehr076]

Here is the correct schematic of the Pulse Star 2 motherboard!

Hello, this schematic is not correct and has many errors.

The good thing about the PS2 Pro is that those machines never break down.
I had dozens of them on the service, but mostly they were very easy services.
Potentiometers or coil connections mostly fail.
But I have never seen any such detector have a main board failure.
Sometimes, due to age, oxidation has occurred on the two-way pin arrays, and it is enough to just separate and reassemble the main board with the front and back.
Big congratulations to the author!

Copied from this link

Original PS2 coils:
25cm coil = 1.5 ohms, 0.611mH
45cm coil = 1.9 ohms, 0.677mH
1x1m coil = 2.7 ohms, 0.361mH (this I am not sure)
2x2m coil = 2.5 ohms, ~1mH

Greetings to all participants of this thread. I have a Pull star II built according to this scheme. I am interested in a 40cm probe. which wire is the best to wind, what is the diameter, and are there electronics, resistors, capacitors, etc. in these probes. Thank you.

please if you have something new sharing on LORENZ in this topic pcb-lorens-5 - Geotech Forums (geotech1.com)

No unfortunately, I don't have more information about the Lorenz Pulse 5 circuit, but I think the op-amps used must be from the TL series.
I think the user named mee has good information about this metal detector, and if he shares it, it will be a great help.

Regarding the pl5 schematic, my information is also incomplete. I checked its schematic before and saw some small problems. Due to the unknown number of some ICs, I left it aside.
I think that if the number of ics is identified, minor problems in its schematic circuits can be identified.
