DUAL CS 627 Q (1981)

 

The Dual CS 627 Q is a fully automatic, Quartz-PLL direct-drive turntable introduced in June 1981, representing Dual’s advanced engineering direction of the early 1980s. Available in elegant Satin Metallic finish, the CS 627 Q was housed in the company’s specially developed HDC (High Damping Compound) plinth, designed to minimize structural resonance and external vibration. Four integrated, height-adjustable shock-absorbing feet further enhance isolation and stability. At its core lies the electronically controlled EDS 502 direct-drive motor, governed by Quartz PLL speed stabilization for exceptional rotational accuracy. When Quartz lock is disengaged, the turntable offers a generous ±11% variable pitch control, allowing precise speed adjustment. The CS 627 Q was factory-equipped with the Ortofon TKS 55 E cartridge featuring an elliptical stylus, mounted in Dual’s newly developed U.L.M. (Ultra Low Mass) tonearm system. This ultra-light arm design minimizes....

SABA HiFi-350 (1981)

 

The result of state-of-the-art technology: the SABA HiFi Series 350. Introduced in 1981 it promised a new benchmark in HiFi technology – inside and out. At just 35 cm wide, the four components deliver precision performance, perfectly matched to each other. Its dimensions (smaller) and qualities (better) were made possible by a new technology: The HIGH-SPEED-CONTROL B power amplifier circuit.

The technology of the individual components:

Integrated Amplifier MI 350: 2 x 50 W music power (2 x 35 W RMS). Output power readable via a five-LED chain. Input for turntables with moving magnet or moving coil cartridges. Connection options for 2 tape recorders or 2 cassette recorders (also combined) and 2 speaker groups. Tuner MT 350: Three wavebands (FM, MW, L) and quartz synthesizer tuning for pure sound and quartz-accurate station storage. Manual and electronic station search. 7 (dual-assignable) station buttons. Cassette deck CD 350: For metal, chrome, and standard tapes. Soft-touch controlled transport; a light touch is all it takes to perform the desired function. Automatic scan for easier location of specific recordings. Fluorescent indicator for monitoring the recording level. Tape counter with memory function, mute function, and Dolby noise reduction. CSP 350 turntable: Tangential tonearm, fully automatic, and direct drive. Pitch control fine adjustment and luminous strobe indicator. All functions operable with the dust cover closed. Finish: nickel silver. Dimensions: Tuner: 35 x 6.5 x 24 cm Amplifier: 35 x 6.5 x 24 cm Cassette deck: 35 x 12.5 x 24 cm Turntable: 35 x 15.5 x 35.5 cm (W x H x D). The TU-35 (white) and TU-355 (wood) racks were sold separately while the matching loudspeakers were the B-3500.

SONY STR-7800SD (1977) | LEC Transistor

The STR-7800SD introduced by Sony in 1977 seems to be a rather rare unit that was aparently only distributed to the U.S. market. According to a Sony advert from 1977: "Even before you switch on the STR-7800SD receiver, it'll be receiving. Receiving oohs and aahs." It continues by saying: "...it is the finest receiver ever designed by Sony." The 7800 puts you on the receiving end of the most tomorrow-looking technology available in 1977. The 7800 brings power to the power-hungry, and can even make the mild-mannered lust for power. Rated at 125 watts per channel, it's powerful enough to drive any speakers-satisfy any need. The 125 watts, minimum RMS at 8 ohms, is from 20 to 20kHz-with no more than 0.07% Total Harmonic Distortion. How this combination of power and low distortion was achieved, is an example of Sony's engineering muscle. Starting with the toroidal transformer. A more efficient structure, it fully exploits the high-performance power amp. As do two over-sized capacitors, each 22,000uF. So the feeling of power throughout the frequency range is unmistakable. You'll receive tuning that'll leave you swooning. FM circuitry found usually in separates appears in the 7800. Pardon for the initials, but MOS FET's are used in the FM RF amplification. The result: good linearity, low noise and high sensitivity. For FM Dolby listeners, a complete FM Dolby noise reduction system is available, to minimize noise and overload distortion. A Multipath switch and meter indicate optimum antenna orientation, thereby reducing distortion. An LED dial pointer doubles in length when an FM signal is received for easy tuning. You'll receive a pre-amp that's pre-eminent. High marks for Sony's Low Emitter Concentration (LEC) transistor. Designed, made by, and exclusive to Sony. It guarantees low noise, and a wide dynamic range. It also keeps RIAA equalization to within ±0.5dB. You'll receive power. And the means to control it. The pre-amp section also gives you the control you need to keep all that power in line. A presence switch is a special present: it lets you equalize the mid-range. Importantly, the 7800 was built with a Professional Attenuator Main Volume Control. It eliminates gang error between channels. Some input on the inputs: Phono 1, Phono 2, External Adaptor, Auxilliary, two tape decks - and tape-to-tape dubbing facilities. Specifications: Continuous power: 2x125W (RMS, both channels, 20-20.000Hz, 0,07%) | THD: 0,07% | Dimensions (W/H/D) 490x170x515 mm | Weight 22,8kg | Original sale price 700 US-$
