Who's a good tech?

I need a circuit drawn Using a 12 V DC 8 AH batteries, zener's and
components to get 9 Volts DC for a 1amp load.

And 7.6 Volts DC for a 2 amp load.

Would some one draw one?

You will need a MJE3055T transistor(Q1), a 1N758A(Z1),and a 100 ohm
resistor(R1) for the 9 volt out.
the 12v input goes to the collector of Q1, the output 9v comes from
the emitter of Q1. Tie R1 between the collector and base of Q1 and tie
the cathode end of Z1 to the base of Q1 and the anode end of Z1 to
ground. You should also add a capacitor(like .01 or .1uf) from the
emitter of Q1 to ground. You can use the same circuit for the 7.6V but
change Z1 to a 1N756A . R1 stays the same. You can get all of these
parts from www.mouser.com There is no minimum from them.
See if this helps
