I cant help you.I sold that original pcb month ago. BSR51 could be replaced with BC517. Watch for different pinouts. I heard various comments from various people who bought Coinseeker from Bulgaria.Not working as advertised.Not working even close as original Relic Hawk. That's all i can say for now, no news yet.
Not secret...why should be? But it is a way off topic here! Don't you think? Friend visited me. I gave him that pcb and broken Troy Shadow X3 and few other things...he gave me also few things... No money involved. We exchanged my scrap for his scrap. He left happy...i stayed happy. Simply as that.
Hi Eugene.
For me it is a large schematic so we need a big pcb (for through hole components).
I study a little the schematic and i saw that it is better to make 2 pcbs as sandwich.
So i will start slowly-slowly to design the first pcb....
GEO , GREAT !!!!!!!! LOOKS LIKE THE POWER SUPPLY WILL USE ONE BOARD BY ITSELF. HOPEFULLY NOT ANY NOISE PROBLEMS BY STACKING BOARDS TOO CLOSE TOGETHER. I HAD TO BUY A PRINTER-SCANNER TODAY TO COPY SCHEMATICS. I CAN SEE BETTER ON PAPER WITH MY GLASSES,THAN TRYING TO SEE FROM COMPUTER. HAVE A GREAT SUNDAY....................EUGENE
I am also very interested in this. But..same as bulgarian guys, i would also avoid all those switching mods. To much complicated for amateur like me. We better choose one proper mode and "cut" schematic, make it simplier. I remember never used all modes at original RH. So bulgarian idea is good, only pcb i dont like. They "overmodded" it to much. Regards!
Why? My experience in drawing new pcbs for already existing detector sometimes is very painfull. In Minelab they did it smt. We want to do that through hole here. Personally i doubt that we gonna succeed to make it properly. To work without internal hums and intermodulations. At the end it will not work good.Trust me. Just keep in mind how many switches and pots it has! Bedlam of controls! All must be "calculated" and routed very well on pcb! Remember that. To much job and success not guaranted. So better let's reduce this again, but also let's try to do that much better than bulgarian guys did.
Oh one more thing; this may help a bit: i am not sure about original ic's . Surelly not about all in original RH. But i am sure about some of them; 4024,4053,27M2,TL074,4066,LM339 and LM393. Which one is where on schematic? I am not sure.No doubts about 4066,4024 and 4053, but op amps....? Not sure. Oh yes; NE5534 is for sure front end! This i am absolute positive! If this helped...fine, if not....sorry.

Hehehe
Hi Ivica. No problem about to build a simplier detector.
But what would you like....... for small objects.... (small coins), for medium or for big objects (treasures)........
I had the same opinion with you but i have not the answer

You are not so old so your eyes are OK. My eyes are noy so good so i like the through hole pcb.....
A good pcb will have large dimentions, so i said that i will try to make it a sandwitch with 2 pcbs. I don't afraid...... i believe that i will construct a very good detector. It is time to try it.......
