TESORO GOLDEN SABRE

R29 and R31=1M. On the PCB TGSL-EDU C14 and C17=22uF + 22uF are in series = 11uF. I recommend everyone to have this PCB.Capacitors by substituting these series 10uF + 10uF= 5uF.

The biggest secretis the coil.Theyhave to respectthe inductancesand the cancellation ofthe coil.Alsoyou have toreplacethe values in thePCBunder this scheme.C17a, b.C14a, b.R29, R31.That'sthe whole secret.

Ok, I see R29 and R31 are increased in value but C14/17a,b look to be the same. What am I missing?

Good test.

So whats the secret, is it a bought coil or home made?

Thanks guys for answers,but it was my coil now i have to find out why is the detection is sooooooo low.

[der_fisherman]

Well that is telling your oscillator, negative power supply and to some extent the audio circuits are working properly. If they were not working, you would not get sound either. So you need to look elsewhere.

Now try breaking the signal path by unplugging something like the LM308's and see what happens.

Do turn power off before popping the chips, its safer....

I cannot use my pc scope,now i have -6.22 volts on pin's 4 but i have a continous sound.What could be the problem i'm totally confused

please
I now do not know who or pcb scheme to take to make the detector tgsl

ivconic eduardo or other

and what changes do I use

Thanks in advance

TGSL-EDU,Silverdog Kit.

[kliner]

I built the kit from Silverdog, its tried and tested by a lot of people, you can't really go wrong

Thanks man , i have it.I will find the problem i hope,thanks again.

Best thing to do might be to download the TSGL 101.zip document under the TGSL complete details section. From there you can troubleshoot your board by comparing what you see at different test points.
