Hi Galal
The most common fault for no or lack of -5v on the tgsl build todate is the transistor pinout connections there are at least 4 different common pinouts on those transistors infact me myself got caught out with the very same thing in the early days.
What you need to do is read all the information on the transistors and google them for pinouts.
Ie: could be 123: EBC, CBE, BEC ,CEB the first two combinations are the most common depending on manufacture.
Theres somewhere on the earlier part of the TGSL forum where the likes of me, Ivonics and a few others grabing them from are stocks and comparing the different pinouts, and we were shocked at the amount of variations.
By the way your not allowed to give up and throw in the towel, we dont except failure in Geotec, we just carry on and make things work.
If you got problems with id post me all the markings on the trs and will check them out for you.
Regards
