Eureka !!!!!!

I've just realised my mistake- I've put the CA3140 in the wrong way round.

I looked at the notch on the PCB layout for IC4 and thought it applied to IC7. I can now see the smaller notch applting to IC7 at the other end. Doh !!!!!!!!!!!!!

Will I have damaged it by doing this ?

I'll now try out my de-soldering skills !

Paul, perhaps you should check if you've fallen into the same trap. (might be a Golf owners thing).
