morning guys

I have a cobra uk25 LTD ST ( sound tracker)... with no sound from speaker..or from extension speaker...!!
tried : new speaker
new audio chip
several cobra mikes ( off known working radios)
When extension speaker is plugged in and volume is turned up full you can just hear a very small hiss from it.
I've looked on line, but the schmatics dont match this radio....only the old version..... does anyone have any ideas or a link to the correct schmatics, I'm pulling my hair out with this one, and dont have much left too pull :crazy:
Thx in advance
