Wega Mini Modul 205
The Wega Minimodul 205 was a set of mini stereo components from the year 1980. I believe they are re-branded Aiwa Series 22 components. Shown here is the 205-CA Control Amplifier, the 205-PA Power Amplifier (2x30W Sinus, 2x40W Musik), and the 205-TD Tuner. Each component is 205mm wide, hence the name.
Not shown here is the 205-C cassette deck, and the 205-A which is an integrated amplifier that can be used instead of the 205-CA and 205-PA if you did not need as much power. It has 2x16W Sinus, 2x18W Musik.
