TEAC AG-790 Stereo Receiver, 100 WPC, Phono, Made in Japan

TEAC AG-790 Stereo Receiver, 100 WPC, Phono, Made in Japan

The TEAC AG-790 is a robust, 100-watt-per-channel integrated stereo receiver built in Japan in 2005, when TEAC was renowned for delivering balanced, neutral sound and reliable analog electronics. Originally retailing for $600–$650 USD, this is a solidly-engineered piece that combines AM/FM tuning, a proper moving-magnet phono stage, and straightforward amplification in a compact, user-friendly package. It’s an excellent hub for a vinyl-based system or a secondary music zone, delivering honest sound without unnecessary complexity or hype. This unit has been thoroughly tested and verified fully functional across all circuits; the tuner locks cleanly, all inputs respond smoothly, and the amplifier drives speakers with control and authority. Cosmetic condition is good with light signs of age and use.

The AG-790’s architecture emphasizes simplicity and transparency. The phono input is designed for moving-magnet cartridges with 6.5mV sensitivity and a 22-kilohm impedance, providing quiet, dynamic vinyl playback from turntables without requiring an external preamp. The line-level inputs (CD, Video/Aux, Tape Monitor) operate at 230mV sensitivity and a clean 90dB signal-to-noise ratio, so modern digital sources remain transparent and resolving. Frequency response extends from 20Hz to 35kHz with total harmonic distortion held to just 0.05%, ensuring the receiver itself remains sonically neutral—what you hear is your source material and speakers, not coloration from the amplifier.

The AM/FM tuner features 30 presets each for FM and AM stations, quartz PLL synthesized tuning for stable, accurate reception, and a mechanical tuning dial with smooth manual or automatic search modes. The output section uses discrete transistors in a simple, proven design that has earned TEAC a four-decade reputation for reliability and straightforward engineering. The amplifier is rated to drive 100W per channel into 8 ohms and up to 100W per channel into 6 ohms, with enough reserve to handle most speaker loads without strain. A front-panel loudness button compensates for reduced ear sensitivity at lower volumes, making late-night listening more satisfying. Bass and treble tone controls allow gentle EQ adjustments, and an A/B speaker selector switch lets you drive two separate pairs of speakers (though not simultaneously).

The front panel layout is clean and logical: input selector buttons for Tuner, Phono, CD, Tape, and Video/Aux; a large jog dial for volume control; bass/treble/balance adjustments via the same knob with mode buttons; sleep timer; loudness; and A/B speaker switching. A full-function infrared remote control is included, providing wireless operation for input selection, volume, and tuning. The rear panel includes 5-way speaker binding posts, phono RCA jacks with a dedicated ground terminal, line-level inputs for CD and tape, a tape monitor loop for outboard processors, FM/AM antenna connections, and a pair of switched utility AC outlets that turn on and off with the receiver—ideal for powering a turntable preamp or powered subwoofer.

Build quality is typical TEAC: solid aluminum chassis, thoughtful internal layout, and components chosen for longevity. At 7.4kg (16.3 lbs), the AG-790 is substantial enough to feel well-made yet light enough to integrate easily into any system. The faceplate is brushed aluminum with clear, legible labeling—an understated design that has aged well and fits naturally into both vintage and contemporary shelving.
