Another Mosfet Boost Question

[tcobretti]

Can I make this circuit run on 12v?  I have a car cd player that has RCA inputs, but they have a very low level, so I'm thinking about making a couple of Mosfet boosters (stereo) to boost the levels and would like to power them from the car's electrical system.

What do you guys think?

You could always use a 9volt regulator, no?

  I'm not certain about the zener protection diode, I think it only sees much lower than supply voltage.
  The other components should be fine with 16v, [you'd have to measure the car battery during end of charge cycle to get an idea what the actual max voltage would be] except the capacitors whose ratings are probably printed on them, always use caps rated for more than the voltage applied to them.

It will run on 12v with no changes.
