RA-Twin II, $39.00 →AKAI AT-K03 AM/FM Stereo Tuner – Digital Servo Lock
AKAI’s digitally tuned FM/AM receiver from 1980 offers precise station access and excellent reception quality in a compact package. The synthesizer-tuning system locks stations with servo accuracy, eliminating the drift and instability of analog tuning mechanisms while delivering clean, noise-free audio.
This unit has been thoroughly tested and verified: all tuning functions operate smoothly across both FM and AM bands, frequency lock engages reliably, and audio output delivers clean signal to any amplifier. Cosmetically, this player presents in good condition with functional display window and normal signs of age appropriate for a 45-year-old component.
The AT-K03’s standout feature is its 1.9µV FM sensitivity—excellent performance that ensures strong reception even in weak-signal areas or with modest antenna systems. The 73dB signal-to-noise ratio and 0.12% distortion deliver notably clean audio free from the background hum or hiss common in budget tuners of that era. Frequency response spans 30Hz to 15kHz, capturing the full range of broadcast content. The 1000mV FM output (300mV MW) integrates easily with any amplifier or receiver.
Front-panel operation is straightforward: large, tactile tuning buttons with digital frequency display showing exact MHz/kHz, dedicated preset buttons for favorite stations, and a clear AM/FM band selector. The numerical keypad enables direct station entry. RDS was not yet standard on Japanese tuners at this price point, but the servo-tuned mechanism provides rock-solid frequency stability once locked.
At 2.9 kg (6.4 lbs), the AT-K03’s compact metal chassis reflects efficient 1980 engineering, making it ideal for shelving beside vinyl turntables or integrated amplifiers. Power consumption is modest, and the clean industrial styling complements most vintage audio systems.

Audio Reflex ART-600 Analog AM/FM Tuner – Rack Mount
An analog AM/FM tuner with rack handles and a weighted tuning knob that spins with real flywheel inertia. Separate signal-strength and tuning meters, an MPX filter and FM muting for the weak stations, and a front-panel output level control for matching it to an amplifier or feeding a tape deck. Built to match the Audio Reflex ARA-335 and ARA-655 sold in Canada.
AKAI AT-K11 AM/FM Stereo Tuner – Professional Build Grade
A 1981 analog tuner with a mechanical servo that locks onto a station and holds it, so there is no digital drift to think about. 65dB signal to noise on FM, 775mV out on FM and 250mV on AM, into a single RCA pair. Nearly ten pounds of chassis, heavier than this end of the range usually got. Tested across both bands; good cosmetic condition.
Sony ST-2950 SD AM/FM Stereo Tuner – Walnut Side Panels
Two microvolts IHF sensitivity and 73 dB signal-to-noise, with FM distortion at 0.5% mono and 0.7% stereo — enough front end to hold a weak station cleanly. Silver faceplate, illuminated dial, and the original faux walnut side panels. Made in Japan between 1976 and 1979. Tested and verified working; good cosmetic condition.
Akai AT-V04 FM/AM Tuner | Digital Synthesizer | Made in Japan
A digital synthesiser tuner with a traditional analog knob, stepping in 0.05 MHz on FM and 1 kHz on AM — fine enough that it works as an AM DX receiver and not only an FM tuner. Seven presets for each band, separate local/distance switches for FM and AM, 300 and 75 ohm antenna inputs, and a rear output level trim. Built in Japan, 1980 to 1981; tested here.
Marantz Model 104 AM/FM Tuner — Made in Japan, Excellent
We sold this tuner ourselves and it came back through our Perpetual Trade-Back Program — so we know what it was when it left, and it has been through our bench again since. A 1976 Model 104 in excellent cosmetic condition: silver face, blue dial lighting, made in Japan.
Braun Atelier T1 Slim AM/FM Tuner — 9 Presets, Quartz, Japan
An analogue tuner given a quartz-referenced five-digit readout — the precision of a synthesised design with a real analogue front end behind it, which tends to hold a weak signal more gracefully. The nine presets are not memories: each station button carries its own tuning adjustment, set by hand with a small screwdriver through the panel, so it is effectively nine little tuners in one chassis. Made in Japan, 445 mm wide and 70 mm tall to match the Atelier deck. Good condition.

A plain digital AM/FM tuner built around a discrete output stage. FM stereo sensitivity of 47 µV, 50 dB separation at 1 kHz, 60 dB AM rejection and 80 dB image rejection; AM useable sensitivity is 10 µV. Digital display with preset navigation, and the original remote comes with it. Seventeen inches wide and 4.8 lbs.
AKAI AT-A1 AM/FM Stereo Tuner – Ultra Slim Profile
An analog tuner from 1980 in a chassis 50mm tall — two inches, which is about as thin as a full-width component gets. Needle-pointer dial with a printed scale, an AM/FM selector, a single RCA output, and nothing else. Tuning engages smoothly across both bands and the output is clean. Condition good, with a clean front bezel and honest age on a 45-year-old component.
