TEAC Z Series (1983) - Made in Japan by Fanatics

cassette deck

The TEAC Z-7000, Z-6000 and Z-5000 are Masterpieces in cassette reproduction technology introduced in 1985. Here are some higlights of the incorporated technology. For high transport performance the Z-Series transports are all constructed on a solid diecast chassis - highly resistant to vibration, resonance and warpage. In the Z-7000 and Z-6000, three independent high precision motors are built onto this chassis: an FG servo brushless direct drive capstan motor and two coreless direct drive reel motors operating in a dual capstan closed loop system. The Z-5000 achives similarly high performance with a two-motor transport consisting of one direct-drive motor driving a single capstan, and an independent DC motor powering the reels. 

In the Z-7000 and Z-6000 the playback head is a top-precision ferrite design, while the recording head is formed of sendust. The Z-5000 offers essentially the same three-head system, but with TEAC original hard permalloy formulation. Perfect record bias, level and EQ are obtained by the Z-7000 with an automatic calibration system while the Z-6000 and Z-5000 feature a precise manual calibration system. All decks feature Dolby B, C and dbx noise reduction circuits. Real-time tape counter, 30-sement fluorescent peak level meters (14 segments in the Z-5000) and a series of convenience and sound features are also included for tape enthousiasts.

Technics SP-10MkII (1975) - Apex of Direct-Drive Turntables

turntable


Technics announced the development of a direct drive turntable for the first time in June 1969, and decided to launch a product under the model name SP10 in June 1970. The SP10MkII is a model refined by adopting the latest quartz lock control system in the SP10 also improving each component.

According to the Technics History page:
"The SP-10MK2 direct-drive turntable was evaluated highly as a global standard turntable. With a powerful brushless DC motor, it realised an astonishingly large startup torque of 6 kg-cm to drive the extra-heavy 3-kg turntable platter to the rated speed in a rotation angle of 25 degrees and in just 0.25 second. The powerful rotation torque maintained constant speed against a braking load of 5 kg-cm. This high basic performance combined with quartz phase-lock control assured stable spin with a rotational fluctuation of 0.002% and wow and flutter of 0.025% WRMS. The brake system combined a mechanical brake and an electronic brake to halt the platter in only 0.3 second. Strobe marks were engraved on the platter edge to show rotational change through the window located on the front part of the cabinet. The SP-10MK2 also featured extensive anti-vibration measures. The cabinet was a rugged die-cast. The bottom side of the platter was covered with a rubber sheet. The SP-10 Series was favoured by professionals the world over for its high reliability."

Technics RS-1030US (1975) - The Unknown Classic

reel to reel


The Technics RS-1030US was introduced in 1975 as a semi-professional tape recorder. It was situated below the RS-1080U studio recorder in the Technics model range while the RS-715U (a more popular model) was intended for home users. The RS-1030US is a 2-track master recorder running at 38 cm/s speed but is also fitted with a 4-track playback only head for compatibility with tapes recorded at 19 cm/s. The RS-1030 mechanism features a 8/4 poles dual speed hysteresis synchronous motor for belt driven capstan and two 6-pole induction motors for fast winding. Specified frequency response was 30-27,000 Hz (+/- 3 dB, 38 cm/s) while wow & flutter was 0.08 % (38 cm/s). The HPF (high pressure ferrite) heads had a 10 year guaranty offering a 58 dB signal-to-noise ratio at 38 cm/s. The deck could also be operated via the optional RP-9103 wired remote-control.
