- If I understand you right, you want to get 12 volts out from something
- that has a 9-volt power supply.
-
- That's not an amplifier. Amplifiers produce output voltages no higher
- than the power supply voltage.
-
- What you want is to convert the DC into AC, run it through a transformer
- or a diode-capacitor voltage multiplier, and filter it back to get smooth
- DC again. That kind of circuit is called a DC-to-DC converter.
