Hello sirs.
At once I apologize, that has not answered at once, job..., job... get tired. I shall necessarily answer everyone who has written to me.
Shall try to be registered at a forum from another Mail. If not it will turn out, I shall address for the help to you.
Question to Darko. You have photo PCB T.Lobo?
I have written to you four letters, unfortunately probably you have not received?
Sorry.

Sorry, I don't have any photo of Lobo PCB. I had to redrawe schematic from one I found here in forum. My yahoo e-mail is: [email protected].

Hi Darko.
Has sent you still circuit Lobo, to me her has given Ciklon.
If not it is difficult, put on a forum please.

If I understand you right, you ask for jpg of Lobo circuit drawing. Here it is.

Hi Vladimir,

I hope finally I understand what you mean. Ok, if you send me files you got from Ciklon I will put them here. Sorry for misuderstanding you. Are you got files I sent you on your mail?

Best Regards,

Darko

Hello there. when i bulded my TGS i had a very good results, untill i made NF amplifier with integral TDA. I lost my discrimination at small objects. Discrimination exists untill i turn potentiometar on max. I had -6.2V and now i have -5.9V, i returned MPSA13 and these rusults are with this Transistor. I checked all integrals, and FET transistors but results are bad as they where.Im interested in max range for TGS with 25cm sonde?
And what do you think i should do to remove this failure in my TGS?
I had a max range 80cm at larger objects.

Regards Dino :P

Hi Dino!
I never liked any of suggested audio NF amplifiers here. Original audio stage with MPSA or whatever transistor showed the best performances so far.
This is not about, just simply to amplify signal. It is quite different approach.
There are 2 basic amplifying principles: voltage amplifying and current amplifying. You just can not mix those priniples. My english is not so good here, for me to give detailed explanations on this. But it is easy to search internet and find some articles on this.
TGS has rather simple yet hard to mod audio! Keep it as it is for now.
You lost discrimination?
OK, for a start assure proper voltages; +8v and -6.xxv.
Further investigate arround Disc&GEB stage. Dont put 10K resistor parallel to 100K Disc pot, as earlier suggested. In most of cases you will loose disc.
Measure current draw. Must be 30-40mA with no detection and 50-60 with full detection, meaning loud audio.
Let's go step by step;
measure all those, assure all i suggested here and report...
Regards!

Check Potentiometers quality! I had case that brand new 100K potentiometer ( i just bought it) was bad from a start. When connected on pcb i had totally lost of Discrimination!? Later when checked all i found out it was bad.
Again damn suppliers here....

Actually Strujas bought that one

Vladimir I have tryed, but no results,The administrator has banned your email address, give me some other email

Hi Geo,
what about trip to Serbja ? Have you meet Ivconic there ?

And what about your TGS too , any news?

Best regards,
Max

PS: I've made the Vladimir's PCB design... and that way I've now also TGSL , that works good even without "right" components... I'm awaiting for new stuff to put on board...cause I run out of LF353 so I'm using now TL072 there.
