Most likely an assembly error.
Sorry, this forum does not allow picture uploads
If you can provide LINKS (e.g. by using a free online picture base) to HI-RES and SHARP pics of your assembly (both solder- and component side)
then we can take a look and provide some feedback.
hi thanks for getting back to me i have taken photos hear is the link photobucket.com/k6080 hope thay are good enough only got a small camera i did my best thanks not posted photos like this before hope it works new to that as well thanks
Soldering technique looks OK, however, due to poor picture quality, it is impossible to spot e.g. a short or bad soldering.
Component placement looks OK. Unable to see if TIP 142 & TIP 147 have not been swapped? Same for the small signal transistors.
Make sure power supply is within specs.
Use proper heatsink
Make sure metal part of both power transistors are electrically isolated from eachother.
