LM7815 voltage regulator

adrian sphank said:

C1 = 470uf
C2 = C3 = C5 =0.1uf
C4 = C6 = 100uf
R1 =R2 =IK
Transformer = 9v – 0 – 9v
REG 1 = LM7812
REG 2 = LM7805

Circuit attach will produce 12v and 5v at the output.
How do I change this circuit to get a 15v and 5v at the output?

I know that LM7815 voltage regulator will produce 15v at the output. But how do I implement LM7815 to this circuit?
