Here is Ivconic's last TGSL schematic (ExpressSCH format) edited to make it easier to link with ExpressPCB software. Fixed duplicate part numbers and some part relabeling more similar to other TGSL schematics.
I also changed transistor pin numbers to try to be compatible with ExpressPCB package styles according to spec sheets I found online. But don't trust them much, you must check your own parts as always.

Hi everybody!
Building my first TGSL right now. Using Max schematic posted at page 130.
I have a Tesoro Cibola, which also runs at 14 KHz, so can i use a Cibola coil with TGSL?
my scheme at the moment:

Hi
Hi,
Ivconic.
I dont wanna rush you or spam the tread.But I am curies about your last audio thuning.Can you post some details.Lat are the last results.The 1265 one
ThanksComment

Why not? Does any Tesoros original coil will fit?Originally posted by ivconic View Post
I do not have any measurement instruments except cheap china multimeter.
Are there any way, i can built a coil without 2-channel oscilloscope?Comment

What details? All the details are posted. You have TGSL schematic and you have audio part schematic. Also you have textual explanation. So what other details you expect?Originally posted by tiktak View Post

Yes you may use original coil form older Tesoros, but not from Cibola,Vaquero,Tejon and Compadre and uMax series. Any other original coil except TGS's will have to be checked for connector wirements also.Originally posted by Beeter View Post
At newer Tesoro machines setup is quite different than at older. Coils are much,much different. So i dont think that you can use coil from new serie with TGS/TGSL.

TESORO GOLDEN SABRE
A Better choice , is to build the "Tesoro Eldorado" , it was just Finished by Ivconic !!!! It sold for $459.00 u.s. dollars at one time ....... A much better project to build !! All information is on this Geotech Forum Here and you will have less headaches...................Regards..........Eugen e52Originally posted by ivconic View Post

Hi Stevan maybe TİKTAK wonder ;
Ha, i knew it! Today i made separatelly 1265 audio stage from schematic above and connected it to TGSL. It is working like hell! Just as i assumed; it is giving to TGLS quite new dimension. Now TGSL audio is extra strong and adjustable, also very rich and it has also sort of "bang" at clear signals!!! Ha,ha,ha! I wasted so many days trying to modd TGSL's audio...but all the time i had ready solution right in front of my eyes! Sheeesh!!
I had fear to meet some signal level isssues here, but i didnt. All is working perfectly from a very start. At TGSL's last stage, LM358 there is 27K resistor goes straight to MPSA13 base. I disconnected MPSA13 and composite signal from 4024, replace 27K with 10K and than connected straight to 1265 audio, and it is working like hell! Excellent! Best audio mod on TGSL so far!
But this experiment has much greater meaning for me; now i can understand much better philosophy of Fisher 1265 too. Actually i thought 1265 has something specially good soluted in previous stages that makes such good audio, such distincive and cognizable specific just to this serie. I was wrong.
Now with this audio stage TGSL is absolute superior in all the aspects to 1265. I will prepare schematic revision and post at TGSL thread...
This was real success..!
But if i wasnt dealing with 1265 last couple days, probably i would never got this fantastic idea....so..again proved that real work,experimenting and hard labour cant be ever replaced with plain philosophy. Proved so many times to me so far....
Now... few questions will remain opened for the future; with setup like this one TGSL will have 2 threshold stages...ha,ha... also 4024 lost part of important role....could be replaced with some simple divider 1/2 to run negative voltage generation stage...
and apetite now grows more; is it easier to achieve audio discrimination (2 tone) etc...etc....huh...neverending story!

Why "unregistered"? Are you the sanctimony mouse and fear to use your registered name? And who the fock is Stevan? You?

Go somewhere and drop.... you know what...

Hi, I´m building a Ivsonics 255mm coil and have some questions about "nulling".
Main body of coil is already sealed with epoxide.
I´m measuring pin 7 of LF353 with scope and source of TR5 with multimeter (200mV range).
The lowest amplitude of signal on scope I can get is about 0,05V, but then voltage on TR5 is -12,6mV. When I adjust coil on 0,0mV on TR5 , signal amplitude on LF is about 1V. I thought that normal is under 0,1V for nulled coil ? The GEB trimmer is on middle positsion. I can adjust voltage with geb trimmer also 0,0mV for first variant, but then trimmer is near to one end. Sorry for unregistred, but if I solve this puzzle, I have time for registering and maybe for some pictures. This is my second TGSL, first was TGS and it works good already about a year .Comment

"...Main body of coil is already sealed with epoxide....
Ha! To late now!
Make another one...Comment

The overlap area is not sealed jet, and can be adjusted. What is normal readings for signal amplitude, when coil is nulled so that it reads 0v on source of TR5?Comment

Dear unregistered robert
Maybe you are get more magnetic field from Coils of your works.
Please relax and get a trip.
if you were here enought time You have to know Stevan.
He is master of tesero on this forum.
I love this forum . please be a gentelman.
Have a good dayComment
