Golden Mask Schematic

[aothunterpl]

Hi, I have a question or changed something in the subject of GM3,4.

Is there someone with you in possession of GM3 scheme or 4?

...

ah I still question where or from whom I buy DVD archive Geotech forums.

What's in the DVD media?

regards ;]

Good afternoon.
My mask works, now being tested.

[württemberger]

Work your Mask4pro now?

[vlamvers]

Thank you all, drew from the board and checked with a green ring on the zener diode is 3.5V. (scheme assembled: a resistor and zener diode, filed 10V output 3.5V)


In the mask 4pro - two zener diode is used: this first, second at 5.5V stands on the battery indicator.

This is my board

I will spread as a complete check.
Power module redesigned, different from the original. Collected at 7810 (10V) and 7805 (5V)
We have hard to find 2 chips used in GM, therefore replaced at affordable.
is a diagram of two amplifiers

You can attach all schemes,please?

I ended circuitry golden mask 4wd pro, all done in diptrace, now ordered the board in China, and gather to test the first 10 units. The size of the board until 10 * 10cm. All depends on the diodes, the original charge was not my why could not it be completely dismantled. Tried to put in place the green - 4148 and it worked, set - diodes with green ring BAV105, BB240 work.

very good
when you test it , put here results/
can you explain about this ? set here mor pics
regards

Black stripe-1n4148
Green stripe -Zener diode 2.7v
Vlamvers can you make more pics on pcb board?

[vlamvers]

Please tell me that the diodes in a gold mask, I see the green and black stripe?

Hi,
GM1+ with manual GB.....Would be perfect.

Is there anyone who can help?

Regards.

All we have to do is to wait for them to post the right schematic or much better to look to other website to search for that and post it here.
