Kenwood KR-V8040 (1987–1988)
The Kenwood KR-V8040 is an A/V stereo receiver from Kenwood's late-1980s lineup, produced during 1987-1988. It sits between the pure two-channel receivers of the early '80s and the home-theater units that followed. The manual covers it alongside the KR-V9040, and the instruction book is explicitly for both models.
The amplifier section is the best-documented part. Two independent sources agree on 120 watts per channel into 8 ohms. hifiengine.com lists that figure at 1% THD, and classicsoundvisions.com confirms 120 watts RMS per channel. Frequency response is rated at 20Hz-20kHz (hifiengine.com lists it as "20Hz-20kHz (dB)" and classicsoundvisions.com as "20-20,000 Hz"). hifiengine.com records total harmonic distortion at 0.03% with a signal-to-noise ratio of 104dB (100dB for the phono stage). Phono input sensitivity is 220mV, line input is 150mV. A period review in HiFI-Stereo (1993, p.80) confirms the 120 W × 2 rms output into 8 ohms from 20-20,000 Hz with 0.05% THD (front).
The tuner section covers FM and AM bands. Hifiengine.com lists FM THD at 0.2% and a tuner sensitivity of 3µV, though the full context (mono vs. stereo) isn't clearly documented. The unit measures 420 × 158 × 438 mm (16.5 × 6.2 × 17.2 inches) and weighs 12.2 kg (26.9 lbs). The original US price was $649.95.
The manual covers both the KR-V8040 and KR-V9040 together. The A/V functions (Dolby surround modes, video inputs) are described in that shared manual without saying which model gets what. The record doesn't clearly separate which surround options belong to which model, so they aren't detailed here.
That leaves a 120-watt A/V receiver from Kenwood's late-'80s transition period, priced at $649.95, with FM/AM tuning and a manual shared with the KR-V9040.
