TECHNICS SB-F1 mk2
is 100% original and excellent working system of the A5 version size which adopted the honeycomb flat diaphragm.
In low-pass equipped with a 12cm honeycomb plane woofer, and the high region equipped with a 2.8cm honeycomb planar tweeter.
Front baffle and oval (ellipse) cross-section, it has to eliminate the disturbance of the frequency characteristics due to diffraction effects.
In addition, by adopting a die-casting cabinet, we ensure magnetically shielded body measures.
Input pins can be selectively used impedance 4Ω and 8Ω.
Usually uses 4Ω for high efficiency regeneration, if you connect to other speakers and the parallel does not take an excessive burden on the amplifier if you use the 8Ω.
Equipped with a thermal relay protection circuit, it has prevented the unit breakdown due to excessive input

1978 was a good year to physically bring to life the most famous slogan of the 1970s : \"Small is BIG\".Technics did its own bigsmallbig with the Concise components while Diatone launched the M01 System, Sony followed two months later with the original Precise P7 system and the Falcon series, Toshiba with the (excellent) System 15 system, alongside Aiwa\'s Aiwa 22 system which would be rebadged by many manufacturers until 1983/84.If we are now used to see minisystems and even -literally- microscopic ones, in 1979 all this was new, quite fascinating and still built like full-fledged components : fair componentry, good mechanics and even high-end features like Pulse Power Supply or elaborate phono MC stages.Needless to say, mini and micro systems would never be built like this again until some (Sony, Teac, Harman/Kardon or Luxman/Alpine) did attempt to make good-sound-in-a-shoebox when the audio market itself was beginning to show definitive signs of weakness in the early 1990s.1978 was the big turnaround and all of the components mentioned above did embody what was to come : small, unobtrusive and easy to use. All that was needed to complete the new picture was... CD.
And CD spells Compact Disc.The C01 series existed in black as well (C01K) but that is an xxxxxx-rare object.Technics in 1994 reshaped the Concise concept with the Concise G (G for gold ; SU-A70, SL-P70, ST-GT70, RS-BX70, SB-M300) but, somehow, few people remember it :)

The stereo preamplifier having the pre preamplifier for MC cartridges. The first rank of MC pre preamplifier constitutes the low-noise transistor from a complimentary push pull, and has realized the low noise, the low distortion, and the low-power-output impedance. The newly developed low-noise transistor is adopted as the first rank of a phone equalizer part. The SN ratio is improved by considering it as the differential amplifier of the Current-mirror load intensity from which the operating current that distorted level serves as the minimum in this can be chosen.
Moreover, the metal film resistor of less than ±1% of deflection and less than ±2% of polypropylene capacitor were adopted as the equalizer element, and the outstanding property has been acquired. The tone control element has adopted as a tone control the type which strays off a signal path at the middle point. In this mode, the frequency characteristic serves as a flat. Moreover, the circuitry consists of low noise ICs. The power transformer is stored in the iron cases excellent in the magnetic shield effect. Moreover, the noise generated on a power-source line is minimum-ized, and the low noise design is put into practice, such as using low-noise type zener diode also for a voltage stabilizer. Power amplifier, the tuner, and the one-touch connexion code that links SU-C01 directly through the shortest course are attached. The die-casting cabinet of precision finish is adopted. The Subsonic Filter is carried.

The stereo / mono-DC power amplifier of the compact size which banished the capacitor from the signal system and obtained the amplification capacity to a direct-current region, and a faithful phase response. A monophonic drive of large power besides a stereo operation is also possible. The uniform dual transistor of the temperature characteristic is diverted to the first rank as differential amplifier of a Current-mirror load intensity. This realizes high direct-current stability and harmful DC drift is suppressed on the minimum level. The voltage amplification stage raises the distorted property of an open loop with pure resistance load, and is driving the driver stage and an output stage to the low distortion.
Moreover, a new study was added also to the operational stability of the power transistor, and the operation stabilized also to the temperature change has been obtained. By adopting a pulse power source, the power transformer is miniaturized sharply. The power indicator by the light emitting diode array which acted to one substrate as Bonn Tyng of nine yellow LEDs and the three red light emitting diodes (they are 24 pieces at both channel) directly is carried. When DC component is inputted from the connected equipment, the protection network which separates a speaker by relay is carried.
This relay works also as a muting of the shocking sound at the time of on/off.

\"Technics has managed to come up with a small tuner package which provides basic and adequate FM and FM stereo reception at a cost that does not penalize purchasers who crave the miniaturized format for their components. Reception using a directional outdoor FM antenna was more than adequate in our listening area, with quality of received programs limited primarily by program material being broadcast. Even 72 dB of signal-to-noise ratio is more effective dynamic range than is usually needed when tuning into current FM radio fare. I have only two minor criticisms of the ST-C01. First, I feel that some sort of signal-strength indicating device (be it a meter or even a series of LEDs) would have been helpful. Second (and this is my pet peeve with lower cost receivers and tuners), I do not care for the coupling of the muting function on the same switch with the mono/stereo selection function. I fell one should be able to enjoy (or defeat) the muting circuitry whether one is listening to stereo or mono. In the case of the ST-C01, I must admit that this last objection is not serious, since the muting threshold was set at a nice low level (3.0 uV, or 14.7 dBf), while the stereo switching threshold occurs at approximately 6 uV (20.8 dBf). Thus, in this case my criticism is not related to inability to receive usable stereo signals while employing the muting feature, but rather the inability to utilize the muting feature when tuning for weak (or strong) mono FM signals. In summary, the Technics ST-C01 is a quite competently designed tuner which offers good value for its price. Its performance compares favorably with standard-sized tuners costing as much—a characteristic which does not necessarily apply to all micro component categories that I have seen thus far.
Description
The Concise Component tuner ST-C01 complements the SU-C01 preamplifier and SE-C01 power amplifier, both in size and performance, because it can reproduce the signals broadcast by the radio station with striking fidelity. Its sensitivity, selectivity, channel separation, signal to noise ratio and frequency response are all of high technical standards. The secret is, of course, in Technics choice of high performance components and advanced design.
