Golden Mask Schematic

[alin2o]

I'm new to the forum and have a goldenmask 1 + frequency of 18kHz and make a few pictures taken with my detector inside. I want to know if you can change the ground on manual and multitone audio discrimination-VCO as goldenmask3. Sockets on the circuit board are free I think work should only switches and potentiometers, a circuit diagram or a picture of connections would be useful for me.
Thank you!

Hello to everyone!
I have a Golden Mask 1 + detector thatoperates on frequency 18kHz and I'm especially pleased with the performance ofdepth, and the detection of small targets. I want to make some changes that areGM2 & 3 manual ground balance and multitone discriminator. On boardconnectors are mounted I think you just have to put potentiometers andswitches.I put some pictures of my detector, can someone help me with thecircuit diagram or cable connection.
Thank you!

Hi Alin2o!
Is posible to make more pics with good resolution on PCB board.I want to see some value of the resistors and caps.
10X in advance!

There shouldn't be a problem. You already managed to attach several images in post #46.

alin2o can you measure this resistor?

[alin2o]

10 kohm (1003)

I have golden mask 1+ and want to upgrade to 3+.You can put a picture of the links between PCBs and potentiometers&switches ?

Hi alin2o, were you able to find out how to do it?

[zelkos]

1003 - it is 100kohm!

Im looking for this bulgarian PI and finaly its here. but where is the schematic diagram?

[zelkos]

Well, big and small gurus have not yet agreed on what is the right scheme, so that we all must have patience...

[AurumKid]

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.

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

Is there anyone who can help?

Regards.
