so for the ground i use, do i use the same ground as what i use for the transister or the one on the part on the back?

what size caps? should it be greater than a certain size or will the supply just be more stable if i use bigger ones? what is the max size i should use? any recommendations on sizes?

and are there any other transistors that can be used the same way, i think maybe the 7804, the 7803 and 7806, i am not sure so someone please correct me

also should i use a small heat sink with it? it is required or should i used one just for insurance?


thx
