Technics was introduced as a brand name for premium loudspeakers marketed domestically by Matsushita in 1965. The name came to wider prominence with the international sales of direct-drive turntables. In 1969, Technics launched the SP-10, the first direct-drive model for the professional market, followed in 1971 by the SL-1100 for the consumer market. The SL-1100 was used by the influential DJ Kool Herc for the first sound system he set up after emigrating from Jamaica to New York. This latter model was the predecessor to the SL-1200 which, as the upgraded SL-1200 MK2, became a widely used turntable by DJs. A robust machine, the SL-1200 MK2 incorporated a pitch control mechanism (or vari-speed), and maintained a relatively constant speed with low variability, which proved popular with DJs.
The SL-1200 model, often considered the industry standard turntable, continued to evolve with the M3D series, followed by the MK5 series in 2003.
Despite being originally created to market their high-end equipment, by the early 1980s Technics was offering an entire range of equipment from entry-level to high-end.
In 1972, Technics introduced the first autoreverse system in a cassette deck in its Technics RS-277US and in 1973 it introduced the first three-head recording technique in a cassette deck (Technics RS-279US).
In 1976, Technics introduced two belt-driven turntables for the mass market, the SL-20 and SL-23. The principal difference between the two models was the addition, in the SL-23, of semi-automatic operation and an adjustable speed control with built-in strobe light. They offered technical specifications and features rivalling much more expensive turntables, including well-engineered s-shaped tonearms with tracking weight and anti-skate adjustments. At the time they were introduced the SL-20 and SL-23, which sold for $100.00 and $140.00, respectively, set a new performance standard for inexpensive turntables.
1 - Electrolytic capacitors are among the most important in an audio equipment and replacing them with high-quality capacitors from the factory will improve the sound quality
2 - Electrolytic capacitors have life of work 1000-2000h then begin to lose their qualities
3 - The use of Audio-Grade Capacitor Nichicon / Elna which are made specifically for audio equipment from high-end will make your machine in good times higher
What is audio grade capacitor?
This is capacitors specifically for audio applications. These are designed to give premium sound quality when compared to general purpose capacitors. Nichicon's MUSE series and Elna SILMIC II, ideally suited for first class audio equipment where qualitative and quantitative characteristics are required.
What you should know when you make replacement
1 Mark all cables when separate circuit boards to avoid confusion in the assembly
2 All capacitors meet on parameters of old, replace them one by one so as not to get confused!
