Step 4How to use it with music
I use mine to watch the waves created by music from my mp3 player
First take an old pair of headphones and cut one off, then strip away some of the insulation.
Now you should have multiple exposed wires, one will be slightly thicker than the others and wll have a thin coating of insulation on it - scrape it off.
Attach this wire to one end of the vertical coil, and the small group of wires to the other end.
Now plug it into a sound source, remember your attaching your mp3 player (or whatever) to a giant coil of wire, and there's chance it could break.

This is because the Horizontal coil is part of the circuit of the high-voltage power supply. Some TVs will work with the Horizontal coil cut. Some will not. If your TV wont work, try connecting a different coil to the wires to keep the mainboard happy. An easy win is to use the coil from another TV or monitor and zip-tie it off to the side.
If you get it working, you now have a vertical line which repeats 60 times per second. You can loosen the metal clamp on the coils and rotate the assembly 90 degrees (turn it to the right, viewed from the back). Now you have a Horizontal line. You can feed signals into the old Horizontal coil, but they have to be amplified first - powerful enough to drive a speaker.
You can use an amplifier like a guitar amp. If you only need to boost a headphone-like signal, you can use the amp built into the TV set. Disconnect the built-in speaker and connect the Horizontal coil instead. Find the wires to the volume knob - one of them is "from" the TV tuner. Unhook that wire and connect it (and ground) to a connector on the outside of the TV. Note: sometimes "ground" is HOT and can shock the hell out of you. Check first. If it is, use a 1:1 transformer from Radio Shack between the knob and the connector.
