Like on pcb just rotate 4148!

Good evening, I found another discrepancy in the schematic and the board. Look at the diode circled in yellow!

My power supply is not ok, I don't have plus 5 and minus 5 volts, please help?

That the 2200uf capacitor goes to the plus 12v battery and to -10v , that's the only mistake, follow the pcb! As for the diodes on the mosfet, it says 51v zener! And you try what you want, the original module uses 51v zpd!
You already have a pcb from one member, I didn't follow the topic in detail, just compare my photo and fix the pcb that I think was put by Dbaner?! And you have gerber ?! Some people could try a little harder..

All correct! PCB!

Thanks for clarify ..many many thanks!

Zener near mosfet I think it should be 170-200V

Mr. orbit, thank you
In the schematic of the motherboard, both the positive and negative terminals of the 2200 uf capacitor, above the speaker are connected to the 12V power supply circuit, which is wrong.
I think the negative terminal of the capacitor should be connected to -10V.

Both 10k and 1k are correct, I opened two modules in one it was 1k in the other 10k. There are no problems with both 1k and 10!

Thank you very much Orbita!

Please post in English, thanks.

Hello, sorry, I was not paying attention, I corrected it.

Please post in English, thanks.

هر دو 10k و 1k درست هستند، من دو ماژول را باز کردم در یکی از 1k در 10k دیگر بود. هم 1k و هم 10 مشکلی نداره!

Hello, you have a very big heart and you are a great person and you sent us the schematic of the metal detector easily, we and God love you, I hope you are always well, my dear, the world is empty, I just have one request from you, please send me the Gerber file, thank you
