Whites goldmaster schematic

[algan]

Hello colleagues, does anyone have a schematic of the Whites goldmaster?

[ivconic]

Wow! Interesting!
I would like to see the schematic too!

i waited first pics of the boards much years. people with a detector do not put pics in the forum but only in privately correspondence by email i get the info.
so you may see the pics now in the Archive. a schematic is still unaccessable, no insiders helpers in the field.

Is it not possible for example that these schematics can be purchased from someone who owns them the archives left over from Whites factory and stored somewhere, can anyone tell where such an inquiry can be made?

I found it in a flea market in China, and it only costs 150 USD. It seems to be in stock from many years ago, and I don't know its performance

open the housing. sniff what smelling. American point or Chinese?

Its origin is in the United States, and it was imported here many years ago. I haven't purchased it yet

Can the GS-IV mechanical selector be replaced with an electronic selector using CD4066?

If you're asking about the Goldscan, this is a thread about the Goldmaster. Start a new thread, and explain what you mean.

I have one of these apart. You can pretty much tell what it is by looking at the part numbers and component layout on the board. I will start on the schematic one of these days.
