Why modeling inside a computer and not using nature itself?
It only takes an electron tube, a resistor from anode to grid (if you want to use low voltage), a capacitor, and a battery with fuse.
And electrons are at our services. Or we to them.
A microphone can be amplified with almost no noise. Great for moving coil or ribbon microphones or crystal or condenser.
A voice can be made loud and big and even more so by adding another amplification stage.
An electric guitar or bass can be made to sound as they should by overloading or not.
Moving magnet or moving coil record player cartridges can be amplified.
Radio stations from around the world can be heard by connecting to an antenna and a coil with capacitor variable reasonant circuit.
The past from distant galaxies can be unveiled by connecting an electron tube to a radio telescope antenna.
An oscillator can be built by feeding the output of the amplifier to the input for synthesizing sounds or rather creating unique real sounds.
High Z studio quality headphones can be directly connected to the anode for amazing big and transparent sound. For example the Sennheiser HD580 with Pleiades Electra I, II or III.
A very suitable electron tube is EF183. It is able to operate on 3 volts at the anode if an anode to grid resistor is connected. It frees electrons.
