Elenco Resistor Substitution Box Kit - K37

Hone your soldering skills and learn more about resistors with Elenco's hands-on resistor substitution box kit. The electronics kit comes preassembled and includes all the parts and instructions you need to complete your resistor substitution box, including a soldering iron and solder.

The completed resistor substitution box contains 24 standard value resistors from 10Ω to 1MΩ. All resistors are 5% tolerance, 1/2watt. Using the provided test leads, you can hook up the box to a breadboard and adjust the dial to the resistance you want. The box will act as a substitute resistor for the times you don't have a resistor on hand or you want to test the effectiveness of a resistor.
