Description: I’m talking about a pre-amplifier, a power amplifier, and 2 loudspeakers (music source: my MP3 player).
The loudspeakers were built by using 4 28 cm Blanda Matt bowls.
The power amplifier is fit inside a 30 cm emptied Lack shelf.
The passive preamplifier, a simple 2 x 20 Kohm stereo potentiometer to regulate the music volume, is fit inside another 30 cm emptied Lack shelf.
