To build a paper-route and push-mower novice transmitter 'kit', you will need a 1950's TV set and an old radio or two. Always check the curbs when you go out to deliver your papers.
The power supply will use the transformer and the 5U4 rectifier from the TV. The audio output tube will serve as a crystal oscillator and the horizontal oscillator tube as the final amplifier (you can use two in parallel for more power if you have two old TVs). An old radio supplies the loading capacitor. If you find the right old radio you might get one suitable for the final tuning capacitor, but since all the grownup hams have ARC-5 parts to burn, one of them will give you one for free if you ask nicely. Coils can be wound on anything tubular with any kind of wire. Even several popsicle sticks can be used to make a cool-looking honeycomb coil. Small parts will come from the TV and radio, of course. Rule 9: there is no value of resistor or capacitor that can't be created from series/parallel combinations of the contents of a 1950's TV set. The transmitter can be built on a piece of wood, an old radio chassis or a cake pan. You will have to buy the crystal ($2.95) with paper-route or lawn-mower money.
