HI Again Ken
I have just noticed that the 51.1K Resistor in the Output section is actually a 51.1 ohm (green, brown , brown , gold , brown).
Do you think this might be the problem here ? I'm going to change it out and make myself a 51.1K

Hi Ken
Have replaced the BC547 in same orientation as per PCB stencil.
I see now that this is the same as a reversed transistor as the BC547 pinout is opposite to the 2N3565.
Still no function.
Constant LED has stopped , don't know if thats good or bad in this case.
Have checked IC orientations. All correct.
I'm completely stumped.

of parts from the board will start lifting tracks.

>Could i have cooked them getting them out maybe ?probably not. Just use a multimeter to check them if you are worried.
>Would it be worth replacing them ?Maybe. It would eliminate the posibility. The down side is constant removal
