Nothing wrong with your schematic. Your problem is with you, you are not listening to what we are telling you. You have an error on your board NOT error with schematic.

Hi Xavier; I follow the TGSL - complete details - version 3.0.zip  documment and I used the pcb from the same document . I tried two PCBs without result the same problem with the two pcbs. all compenents is very good I think there is some missing compenents in the oscillator block or in the clocking signal from CD4024 . this is the compenent placement

I have build this machine three times, I'm busy building another using the same schematic as the one that you have with the exception that I added the two tone mod to mine. You need to check the PCB to the schematic then check all components again, make absolutely sure that the transistor orientation is correct by downloading the data sheet from here.

the problem is either with your PCB or one of your components, I can assure you that the schematic is correct.

  That is a Parts placement. NOT Schematic.  You have something pulling more power then you want.

He posted the schematic in another post but I think that he should post a photo of his PCB too so that we can have a look at it, never know may even find the fault.

I don't know how to explain this to you, there are no components to be changed the problem is NOT an error in component it's in the way you have put the board together. there are NO shortcuts you need to go through it all very carefully and you will find the fault. Post us a photo of your board top and bottom side so that we can have a look at it for you.

 Great Now you got it, do it but take your time, it's not an easy thing to do especially if you have never done this before and even if you have it's never easy to do. Hope that you find your fault.

Don't know if this is your board, or oregondirtfishers, but the one picture has definite problems. See the attachment.

A bad day at gold prospecting or metal detecting is better than a good day at work.
