Below is a link that shows you how to make a simple amplifier for an electric guitar. It uses the LM386 OpAmp chip and runs off a 9 V battery. You can either attach an 8 ohm speaker or use an output jack to another device.
The second link includes instructions and detailed photos.

There are also schematics out there for discrete transisotor amp circuits.
In Middle School we built a 3 transistor amp.

provided which you think of you may play alongside thoroughly. If that appeared possible, then i could attempt a head-pretend: "hear that? -- it quite is the hearth alarm, the hearth branch is on their way. specific, i'm fairly constructive." etc. Failing that, you may could desire to distract the guy in simple terms long sufficient which you would be able to flee and make contact with the paramedics. regularly conversing, although, in view which you have a staggering to no longer be harmed and an criminal duty to shelter your self, it quite is ideal to stay out of somebody else's fantasy.
