This is my first project. This is an audio amplifier, a light bulb as a speaker. I do not know if it will work. What do you think about this? I`m sorry fot the mistakes, but Im from Polish.

This is close. For starters, give the 20V dc supply a ground on the negative terminal. Then you will have an AC wave form through your "speaker." Also, using the collector as your output will give you more voltage. To do this properly, you will need to add a resistor on the collector. Finally, Speakers are AC devices. DC just sounds like a buzz. You will need to add a capacitor before the speaker to block the DC current from getting to the speaker. This will allow pure AC to the speaker. Search my circuit "Booster Pedal for Guitar". It is an audio amplifier using a Line Level input. You will see how using the collector as an output works, and how to set up the DC power supply.
