Historical Significance

Kenwood's KR 720 was built between 1977 and 1979. It belongs to the silver-face KR series, and it sits in the middle of Kenwood's range: near-high-end performance at a price that didn't take a second mortgage. Collectors still admire the build.

Sound Signature

The KR 720 sounds neutral. It doesn't hype the highs or thump the bass for effect. It plays what's on the record, clean and uncolored. The 45 watts per channel drive speakers with confidence, with tight, articulate bass and smooth treble that doesn't tire the ear. Vinyl or FM, the sound stays detailed and balanced.

Maintenance and Restoration Tips

Like any vintage gear, the KR 720 needs a little attention. Controls and switches often get scratchy over time, and contact spray cleans them up. Check or replace the electrolytic capacitors, especially if the unit has sat idle for years. The dial lamp may need replacing. Verify the DC offset at the speaker outputs before you connect speakers you care about. Done right, a restored KR 720 can perform as it did in '77.
