mini hifi


This must be the most sophisticated compact system ever. The Super DIGIFINE SD1 Series was introduced in Europe in 1996. All the components feature a 3.5 mm one piece aluminium front-top panel and a 3.2 mm thick steel bottom plate. The components of this system are:
AX-SD1GD - Stereo Super-A amplifier, 70 W/ch (4 ohm 1 kHz DIN), dual transformer contruction, Compu Link System remote
XL-SD1GD - 1-Bit P.E.M. D-A converter CD player, optical and coaxial output. Dedicated remote
FX-SD1GD - RDS tuner with 40 presets, built in MPX filter
TD-SD1GD - 3 Head (Fine Amorphous) Direct Drive Closed Loop Dual Capstan cassette deck with Dolby B,C and HX Pro, Dedicated remote
SX-SD1WD - Compact 2 way bass reflex loudspeaker, Brass die-cast front panel and solid wood enclosure, Magnetically shielded 13.5 cm bass-mid with Alnico-Magnet designed by loudspeaker expert Dr. Kurt Müller, 2 cm soft dome tweeter, 55-30,000 Hz
All components are 360 mm wide and 129 mm high with depth between 317 and 337 mm. 

The same system was sold in Japan under the Victor brand name and the system was simply called HMV (His Masters Voice). The model names were also different: AX-V1 amplifier, XL-V1-N cd player, TD-V1-N cassette deck and SX-V1A-M compact loudspeaker. Additionally there was available the SX-V7-M floorstander loudspeaker, QL-V1-M Quartz Direct Drive turntable and a later introduced and very rare MD-recorder the XM-V1-N.

JVC DD-V9 (1983) - Closer To The Musical Truth

cassette deck

Superior performance specifications, Special convenience features, Superb sound quality, this is the JVC DD-V9 (Victor DD-V9 in Japan) 3 Head Auto-Reverse cassette deck introduced in 1983. The JVC DD-V9 is the ultimate in convenience and precision - convenience because it records and plays both sides of a tape automatically, and precision because it has three heads. JVC's auto-reverse swivel head features a jewel-lock system (ruby-tipped azimuth adjustment screw) that makes possible to adjust the head alignment for each path of tape travel independently. The three-head design consists of a SA (Sen-Alloy) recording head and a Metaperm playback head, hyperbolically curved for extended bass. During forward play and record, the DD-V9 use a capstan directly driven by compact Pulse Servo motors designed and built by JVC at their own plant. 

The Pulse Servo motor used incorporates a significant amount of technology originally developped for JVC turntables. Technically the motor can be described as a "4-phase, 8-pole, brushless & coreless FG direct-drive motor" The JVC computerized B.E.S.T. (Bias, Equalization, Sensitivity of Tape) tuning system analyzes the electromagnetic properties of any tape and adjusts the deck's electronics for a perfect match - all in about 15 seconds. The fluorescent display will show you remaining tape time in minutes and seconds and various Music Scan modes. The two-colour fluorescent level meters are accurate, easy to read and highly responsive. Each of the bars for the left and right channels consists of 18 segments, and in turn each segment is formed of 20 matrix dots. Less frequently used controls are located on a slide-in/out panel for easier operation and cleaner lines while the optional R-70E wired remote control adds to the list of comfort features.

JVC DD-99 (1982) - Another Step Closer to Reality

cassette deck

When introduced in 1982 the JVC (Victor in Japan) DD-99 promised open reel sound quality with cassette convenience. To achieve this the DD-99 combines such high-technology JVC innovations as a Quartz-Lock, direct-drive Pulse Servo Motor with two new twists: a Double Servo and Multiplied Bridge Drive. Add them to a three-head design using an X-cut SA combination Rec/Play head and the B.E.S.T. tuning system, and you get peerless performance. The Quartz-Lock, direct-drive Pulse Servo Motor improves speed accuracy. Using a low-rpm direct-drive motor, the highly accurate tape transport of the DD-99 is simplicity itself. The coreless design completely eliminates jerky motion called "cogging" while speed accuracy is provided by means of a quartz-referred Double-Servo circuit, together with new "Multiplied Bridge Drive". 

The B.E.S.T. tuning system automatically compensates for any differences in Bias, Equalization and Sensitivity for flat response (from 40 to 12,500Hz +/-1dB) from any tape. It's done by means of a built-in computer and takes only about 30 seconds. Three heads - JVC's exclusive X-cut SA combination Rec/Play head (two heads in one housing), and two-gap SA Erase head - provide two very important benefits. One, it allows you to monitor your recordings as they're being made, and two, it means every head is provided with an optimum gap width - no compromises. The clearly discernible X-shaped core of the playback head eliminates the so-called contour effect, assuring smoother overall response. 

The two motor full-logic control tape transport features a tension stabilizing loop. The supply reel is connected to the takeup reel by means of a belt which supplies the proper hold-back tension throughout play or recording. It's an electrical system, no mechanical friction is emplyed to create tension. Therefore, tension is always uniform, and stability will not deteriorate with the passage od time.

Victor M-L10 - Laboratory Series

power amplifier

The Victor (JVC) M-L10 power amplifier was introduced in 1981 and was based on the earlier Laboratory Series M-7050 from 1979.  The power amplifier is based on the high efficiency class A operation method called "Super A" with zero switching noise. The output stage transistors operates at a constant voltage, only the current is changed, and the whole stage adopts a cascade cicrcuit construction. A distinctive (21 step laquering) mirror finish real wood cabinet is used for both the pre-amplifier and power amplifier. This beautiful Laboratory Series amplifier combo was sold under the Victor brand name in Japan while worldwide it was sold as JVC. Technical data: 160 W/ch (RMS, 8 Ohm, 20Hz-20Khz, 0.002%THD), Dimensions: 46*20.35*41.75, Weight: 28 kg

Summer Holiday and Vintage Portable Audio

Summer Holiday is here so it's time to relax. If you are a rich guy then you simply escape from the Big city.....in a Big way. 


If you are like me, a regular Hi-Fi guy, then you pack your bags (and Hi-Fi) and hit the road.


Finally arrived each one goes it's own way. The rich guy with his Yacht, girl and Boombox while the
regular guy is watching the girls and goes to beach parties.






When your holiday ends and you feel a little bit shrinked, that's because you've stayed too much in the water.


That's all folks.
