LM7808

My voltage regulator broke down and voltage jumped to 10V when testing step 3  In test situation there is no heat sink. I now have a new component to replace it with. Could I avoid this by heat sinking. I have more TDA2822 If this has been affected also.
Thanks for any comments.
John.

Now the PCB is formal.

Thanks,
