LOOKING FOR GOLDSCAN 4 Schematic.

[Jose]

Excuse me, I did not understand the question.
Terminal "D" of J113, is connected in pin: 2; 3; 5; 6 of U10, respectively.
So I have it in my GS4, which is working.

hello jose ... I think I got confused with the answer there I took a picture so you can see how I understood the last answer ... according to your last answer q5, q6, q7, q8 must be modified pin D ... ERROR IN THE SCHEME DE alex? ... Greetings

[Jose]

Yes, it is exactly what you published.
The image below taken from the original, can clarify the doubts.

[ricalbertvig]

thank you very much jose for your clarifications .. in the case of q10 and q9 the pin D If it goes to earth? since by the mentioned thing now I think in q10 and q9 are not correct in the scheme?

[Jose]

For the case of Q9 and Q10, the "S" terminal is connected to ground or GND. The attached diagram is correct, although there could be some error.

hanks José I almost finished the plate and with the space to adapt ne5532 and with the 7660 source I will use instead of ne5532 mcp602 feeding positive and negative with 100 oh

hello jose, I have a problem, I can not find ca85 .. What substitute can I use for ca85?

[waltr]

hello jose, I have a problem, I can not find ca85 .. What substitute can I use for ca85?

Do you mean the OA85 Germanium diodes?

Then try NTE109 or 1N34 or 1N270

[eclipse]

You can use BAT85, but even regular 1N4148 will work.

[Jose]

I used 1N60, because that is what I was able to achieve.

DEAR ALL MEMBERS. PLEAS SHARE Bernte SMD PCB COMPONENTS IN TOP AND BELOW SIDE AND SEARCH COIL DETAIL.

[roda]

all in one

Bonsoir Jose excuse me for my language;
i hope you send me the schematic final for this machine ,with allimentation schematic
it's my first experience , thank you

[eclipse]

Goldscan is very very tricky to get properly working.
I would strongly suggest looking into easier project like Minipulse and Barracuda which do have complete "final schematic"

[ricalbertvig]

Hello, what would be the reason why the regulator 12 volts negative after a while burn, very hot when connecting the coil

[ricalbertvig]

I think it should be because I use a very thick wire for the coil .. I get 1oh the wire is thick 18 .. what wire is the ideal? ... Thank you for any information
