Well, on the zener i measured 12,45V. So it is a 12V I think. Not 15V as I
previous supposed. It power the pins as I written so :

About powers:
LB1612 pin 19 datasheet says 8-14VDC
TC1642P pin 16 datasheet says 5-9.5VDC
C358C pin 8 datasheet says until +32vdc

I could try to substitute the zener with a 7808 ic 1W.
This could keep all is not warm and protect. RIGHT?
