@Nándor :
Do you have the coil connected ?
If not, the oscillator won't run and you can burn the transistors in the negative voltage generator.

[Nandor]

many thanks for the quick answer,you are right it was my fault

[Nandor]

We need a little more information from you. What version are you trying to build?
Don

Hi,i am trying to build this "
TGSL - complete details - version 3" and i don't have scope,but when i measure voltages in IC pins i get +7.8-8 on pin 4 and -2.2 on pin 8. I think that negative voltage is not enough right?

[hugo]

@Nándor : Right. You should be around -6V. Check transistors on negative supply.

According to your measurements, your supply voltages are crossed over. You should have a positive supply on pin 8, and a negative supply on pin 4, not the other way round. I suggest you check this first before investigating why certain voltages seem a bit low.

Ok thanks for answer i will recheck every thing that should help me.

[Nandor]

Hi guys it's me again I have another question.I have solved the negative supply problem now i have +7.8 volts on pin 8 and -6.21 on pin 4 .But i have no sound it's doesn't works.What could be the problem?

Hi Nandor,

Do you have access to an oscilloscope?

Don

[Nandor]

Hi, no i have no scope but i have pc scope.How can i use it properly?It's good?

[dfbowers]

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.

[Nandor]

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

[Nandor]

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

[sekulitatea]

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

[kliner]

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