TEAC - V-9 / T-9 / A-9 Hi-fi set - Multiple models

The Teac Series 9 Hi-Fi Set (composed of A-9, T-9 and V-9) is an iconic line produced in Japan around 1981. It stands out for a futuristic aesthetic of the era, characterized by front panels with orange inserts and very colorful LED indicators, now highly sought after by collectors for its unique retro-tech style. The P9 turntable is sold separately.

The set for sale presents itself in very good visual condition, with small signs of wear highlighted in the photos, which are an integral part of the description. It should be noted that one of the springs of the speaker terminals remains slightly “open” but works perfectly (see photo).

Functionally the set is in excellent condition and the drive belts on the deck have been replaced.

The Teac A-9 amplifier (1981) is an “Integrated DC Servo” component designed to offer high fidelity with compact form and a futuristic look. It is equipped with a DC Servo system: It uses a “Double Integral DC Servo” circuit that eliminates the need for coupling capacitors in the signal path, ensuring deeper bass reproduction and superior thermal stability.

Final Stage: Purely complementary Darlington design, with an armored toroidal transformer that reduces electromagnetic interference.

Phono Configuration: Includes a versatile pre-phono with MM (2.4 mV) and MC (0.5 mV) cartridge selector, with a signal-to-noise ratio of 82 dB and 67 dB respectively.
Technical Specifications
Output Power: 60W + 60W RMS into 8 ohms (20 Hz – 20 kHz).
Frequency Response: Extended from 15 Hz to 80 kHz.
Total Harmonic Distortion (THD): Very low, equal to 0.01% at nominal power.
Damping Factor: 30, which gives a transparent and fatigue-free sound.
Front panel features LED indicators with red VU meters for signal level monitoring.
Tone Controls: Bass (100 Hz ± 10 dB) and Treble (10 kHz ± 10 dB) with slide faders.
Filters and Muting: Includes a subsonic filter (25 Hz, 18 dB/oct) to protect woofers from vinyl disc noise and a -20 dB muting function.
Inputs: Phono (MM/MC), Tuner, Aux, and two Tape inputs with monitoring.

The Teac T-9 tuner (1981) is the ideal technological companion to the A-9 amplifier. It is an AM/FM receiver that marked the definitive transition from analog systems to quartz-controlled digital systems, all focused on signal stability.

Features and Operation
Quartz Digital Synthesis (PLL): The Phase-Locked Loop guarantees that frequency drifts are prevented due to temperature changes, keeping tuning perfectly centered on the desired station.
Preset Memory: Offers the ability to store 10 stations (5 FM and 5 AM), an advanced feature at the time that allowed immediate recall of preferred channels.
Auto Search: Has an automatic scanning function that stops as soon as a sufficiently strong signal is detected.

Technical Specifications
Sensitivity (FM): 1.9 µV (10.8 dBf), making it effective even in areas with weak radio signals.
Signal-to-Noise Ratio: Exceptional for an era tuner, with 80 dB in Mono and 72 dB in Stereo.
Stereo Separation: 52 dB (at 1 kHz), providing a wide and well-defined sound stage.
Harmonic Distortion: Extremely low (0.08% in mono, 0.1% in stereo).
Frequency Response: 30 Hz to 15 kHz (+0.2/-0.5 dB), covering the full spectrum of standard FM transmissions.
Panel and Connections
Display: Digital display shows exact frequency via a bright green numeric display, coordinated with the A-9’s VU meters.
Variable Output: A rare feature is the adjustable output (80 to 2000 mV), which allows leveling the tuner’s volume relative to other sources like the turntable.
Antennae: Supports both the classic 300 ohm twin-lead and the 75 ohm coax cable for FM.

The Teac V-9 (1981) is the flagship of the series from a mechanical standpoint. It is a two-head cassette deck distinguished by superior wow & flutter control, thanks to an internal architecture derived from Teac/Tascam professional models.

Mechanics and Heads
- Three-Motor System: Unlike many cheap single-motor decks of the era, the V-9 uses three independent motors (one for capstan/transport, one for rewind, and one for service). This drastically reduces wow and flutter.
- Permalloy Heads: Uses high-density heads that offer good wear resistance and a linear frequency response, ideal for capturing high-frequency detail.
- Total Logic Mechanism: The controls are touch-sensitive (electronic) and allow switching from one function to another (e.g., from rewind to play) without pressing stop, protecting the tape from snags.

Technical Specifications
Frequency Response
- Metal Tape: 20 Hz – 19 kHz
- Chrome/Cobalt Tape: 20 Hz – 18 kHz
Signal-to-Noise Ratio: 59 dB (no Dolby), rising to about 70 dB with Dolby B active.
Wow & Flutter: Only 0.045% (WRMS), an excellent value ensuring extremely stable playback speed.
Tape Compatibility: Selector for Normal (Type I), Chrome (Type II) and Metal (Type IV) tapes.

Special Features and Aesthetics
Display "Color Blocks": The most iconic element. Two large colored LED bars show peak levels, making recording calibration very intuitive and dramatic.
Fine Bias: Includes a potentiometer for fine adjustment of bias, allowing optimization of recording based on the specific brand of cassette used.
Digital Tape Counter: A green 3-digit LED display, much more precise than mechanical wheel counters.
Timer Standby: Ready to start recording or playback via an external timer.
