Audio Amplifier Kit 1 was tested and designed for use with our crystal radio and radio IC kits. The amplifier should work well with other home built radios but was not designed as a general purpose amplifier for mp3 players, phones and the like. The kit was designed for use with a high impedance headphone or earphone with 2,000 ohm or higher impedance. The kit has been tested with all the headphones and earphones available on our site. Using headphones or earphones with less than 2,000 ohms impedance may work acceptably, however that was not the kits design so performance may suffer.
