Technics ST-S1 FM AM Stereo Tuner amplified by Techies SU-Z35 Stereo Integrated Amplifier from 1980s

The Technics SU-Z35 is a slim-designed Hi-Fi integrated transistor amplifier, produced by Technics in 1984. It comes in two colours, silver and black, and consumes 260W at 120/240V power.
The pre-amplifier section of the SU-Z35 includes inputs for phono MM, tuner, tape, and aux. The high-level input sensitivity is 150mV, with an input impedance of 22 kΩ. The frequency response of the high-level input is 10-80,000 (-3 dB) HZ, and the signal-to-noise ratio is 97 (IHF A) dB.
The phono MM input sensitivity is 2.5mV, with an input impedance of 47 kΩ. The frequency response of the phono MM input is RIAA (±0.8 dB), and the signal-to-noise ratio is 79 (IHF A) dB.
The equalizer section of the SU-Z35 includes tone controls for bass and treble. The frequencies for these controls are ±10 dB/50 Hz and ±10 dB/20 kHz, respectively.
The power amplifier section of the SU-Z35 has two speaker outputs and a headphone output. It delivers continuous power of 32 + 32 Watts at 4Ω and 30 + 30 Watts at 8Ω. The harmonic distortion of the amplifier is 0.03% (40-20,000 Hz) at the rated output.
In terms of physical dimensions, the SU-Z35 measures 16.93 x 3.39 x 9.45 inches (w x h x d) or 430 x 86 x 240 mm (w x h x d). It weighs 10.14 lbs or 4.6 Kg.
Overall, the Technics SU-Z35 is a high-quality amplifier that offers great value for money. Its slim design, along with its powerful amplifier and versatile inputs, make it a great addition to any home Hi-Fi setup.
The Technics ST-S1 is an AM/FM stereo tuner that was released in 1980. It has a sleek and stylish design, typical of the era, with a tuning scale that is analogue. The tuner has a tuning range of 88 to 108 MHz for FM and 525 to 1605 kHz for MW.
The sensitivity of the tuner is 1.3uV for FM and 30uV for MW, which is considered to be quite good. The signal-to-noise ratio for FM is 70dB, which is a good measurement of the quality of the tuner's reception. The distortion of the tuner for FM is 0.3%, which is also a good measurement of the quality of the tuner's reception.
The selectivity of the tuner is 75dB for FM and 27dB for MW, which means that it can pick up signals from a distance with good accuracy. The frequency response of the tuner is 20Hz to 15kHz for FM, which is considered to be a good range for a tuner of this age.
The output of the tuner is 300mV, which is considered to be quite high for a tuner of this age. The dimensions of the tuner are 430 x 142 x 251mm and it weighs 3.8kg.
Overall, the Technics ST-S1 is a solid and reliable AM/FM stereo tuner that provides good quality reception for both FM and MW. Its sleek and stylish design also makes it an attractive addition to any vintage audio setup.
