Kenwood Vintage Integrated Amplifiers

Founded in Japan, Kenwoods parent company began selling electronics in the United States during the 1960s. Throughout the 1970s and 1980s, this company produced integrated amplifiers for use at home. These period stereo amplifiers had great quality and remain highly sought-after, even now.

What are some features of these integrated stereo amps?

Most amplifiers made now are integrated, but this was not always the case. Kenwoods amplifiers became known as integrated because they contain both a pre amp and power amp in a single unit. They also offer true stereo sound.

  • Inputs: These integrated stereo amplifiers feature inputs for phono (record player), tuner (radio), and auxiliary equipment.
  • Outputs: Most units feature a standard headphone jack. These amplifiers are also designed for true stereo. The left and right speakers are each wired from the amp. Other companies often had only one output, and the second speaker fed from the first.
  • Controls: Commonly found controls include the input selector, balance, volume, bass, and treble.
  • Meters: Some models also include power meters. This is one of users favorite features. With these meters, theyre able to tell when the amplifiers reach peak power.
What are some aesthetic features of these vintage amplifiers?

Most of these period integrated Kenwood amps feature a stainless-style metal finish. Usually, the controls share the same finish. On some models, the controls are black. Some models also have wood or artificial wood-grain cases, but these are rare.
