Aimed at Key Stage 3, the Rapid Audio Amplifier Project Kit provides teachers and students with a stimulating and inexpensive project through which to study the subject of amplification. The kits contain a comprehensive selection of components for schools working on audio related projects linked to the National Curriculum. * Students have the opportunity to build a small amplifier, which can be incorporated into a variety of product designs, e.g., as an amplifier for a personal CD / MP3 player so that they can share their music with their friends * The students have a number of design situations to select a starting point from, and they are provided with research topics and background material to help build understanding for their chosen design brief * The student notes provide material for students to explore how a range of simple amplifier circuits work * They also include guidance on the design and construction of speakers * To support students during the construction of the circuit, detailed instructions have been included on how to assemble the amplifier, and how to integrate the circuit into student designs * In addition, care has been taken, through extensive evaluation of the teaching material and PCB designs in schools, to ensure that the circuits are easy and robust enough for student manufacture * A detailed set of teacher notes is available which includes suggested lesson plans and mapping to the National Curriculum * The project notes have been designed for photocopying for class use Each kit contains the following: * TBA820M audio amplifier and IC socket * Resistors, capacitors, and LED * Switch and connecting jack socket * Connecting cable * Speaker and speaker cable * Battery clip * Printed circuit board * Each kit requires 1x PP3 battery (not included) * Supplied in a classpack of 20 kits (includes PCBs), in a 43 x 31 x 7cm Gratnells Tray with lid* * Tray colour may vary. Teachers notes are available to download here. https://elecena.pl/product/27206680/rapid-audio-amplifier-project-kit-pack-of-20-with-storage-tray-includes-pcbs 2024-11-10 https://elecena.pl/product/27206680/rapid-audio-amplifier-project-kit-pack-of-20-with-storage-tray-includes-pcbs 2025-03-21 https://elecena.pl/product/27206680/rapid-audio-amplifier-project-kit-pack-of-20-with-storage-tray-includes-pcbs 2025-09-13 https://elecena.pl/product/27206680/rapid-audio-amplifier-project-kit-pack-of-20-with-storage-tray-includes-pcbs 2026-02-17 https://elecena.pl/product/27206680/rapid-audio-amplifier-project-kit-pack-of-20-with-storage-tray-includes-pcbs 2026-05-20 https://elecena.pl/product/27206680/rapid-audio-amplifier-project-kit-pack-of-20-with-storage-tray-includes-pcbs 2026-07-05 https://elecena.pl/product/27206680/rapid-audio-amplifier-project-kit-pack-of-20-with-storage-tray-includes-pcbs 2026-09-14
