Aurex (1978) - Seriously Modern

Aurex PC-X80AD (1978)

Even though technically is "only a 2-motor 2-head deck" it is extremely well built and it also sounds very good. Here are some technical highlights of this exclusive model sold in very low numbers. (Some say the production number was 130 but a deck with serial number 161 was also spotted). First there is the front panel that is a solid piece of die-cast aluminum. Then the mechanism is bolted straight to the front panel. This is clearly visible by the presence of the mounting bolts around the open cassette bay. The head used is a Sendust head labelled AS (Aurex Sendust). The deck has two transformers - one for audio and one for the tape mechanism. The PC-X80AD has a 3-position tape selector on the front panel for Normal, Chrome and Special tape but, the Special tape position has a switch located on the back panel of the unit to select between FeCr and Metal tape. This makes-it one of the first, if not the first cassette deck with Metal tape capability. All this technological tour-de-force was implemented in support of the adres noise reduction (a Toshiba development) system capable of 84dB signal to noise ratio and a frequency response of 20-20.000Hz with Metal tape. The most visually and technically striking feature is however the level meter. This is a Plasma Peak Level indicator with an unbelievable 201! segments. The open cassette mechanism had also a transparent dust cover that had to be removed by hand. The RM-15 wired remote control was sold separately. Size: 420x148x384mm (WxHxD) | Weight: 12kg | Original sale price: 2500 DM in Germany.

YAMAHA PX-2 (1979) | Heavy Velvet

 

YAMAHA PX-2 (1979) | Heavy Velvet

Brand: YAMAHA
Model: PX-2
Year: 1979

Massively built. Delicately precise. Elegantly styled. That's Yamaha's PX-2 tangential tracking quartz-locked turntable, the flagship of a remarkable new series of turntables from Yamaha. One of the major performance advancements on the PX-2 is Yamaha's unique optimum mass straight tonearm assembly. Among the most significant benefits of optimum mass is that it specifically addresses two of the most critical elements of music signal tonal quality - tonearm resonant frequency characteristics and high trackability with a wide range of cartridges. The PX-2 is also a study in durability with its solid, anti-resonant monolithic diecast aluminum bas.

Technical data:
Type: 2-speed Fully Automatic Linear Tracking
Motor: Quartz-Servo Direct-Drive 
Platter: 310mm die-cast aluminum alloy
Wow & Flutter: 0.01%
Signal to noise: better than 80dB (DIN-B)
Tonearm length: 190mm
Dimensions: 493x156x428 (WxHxD)
Weight: 17kg
Original sale price: 2700 DM in Germany

Victor FF-700 (1976) | Stereo Hi-Fi System

 

Stereo Hi-Fi System

The FF-700 is a unique Hi-Fi system created in 1976 by Victor (JVC - Japan Victor Company). One can clearly see the design ideas "borrowed" from Bang & Olufsen (see Beomaster 6000) and JBL (see JBL Paragon). The FF-700 consists of a 22W/ch FM-AM stereo receiver, a belt-drive turntable and two back-loaded 2-way loudspekers featuring a 16cm paper cone woofer manufactured by Hawley in the USA. Placing the two loudspeakers on their side (and adding a custom stand) creates a visual reference to the JBL Paragon loudspeaker system even if they are technically more simple but still they follow the same backloaded principle.

marantz SD-930 (1983) | Digital Monitoring

 

marantz SD-930 (1983) | Digital Monitoring

marantz SD-930 (1983) | Digital Monitoring

The SD-930 cassette recorder was introduced by marantz in 1983 (November 1983). A lot of confusing and contradictory information can be found about this model, and I'm not talking about information found on the internet but, official manufacturer descriptions. Both the German and English product brochure present this model as having 3-heads but in the same time they present the auto-reverse models also as having 3-heads (Mathematically they all do have 3-heads but they have different functions). Then for even more confusion the service manual says that the SD-930 is a "2 Head System" model... No need to worry though, 1001 Hi-Fi comes to the rescue. The SD-930 is a 3-Head model with separate 1xerase, 1xrecording and 1xplayback head but...there is no monitor switch, yet the inscription on the front panel reads "Digital Monitor Cassette Deck SD930". All clear, isn't it? For whatever reason it seems that the 3-head configuration is only used by the Automatic Compu-Bias System and the MAAC system. The MAAC (Marantz Auto Azimuth Control) system is the highlight of this model. This system is utilizing a piezo-ceramic electric element to adjust the play head for optimal playback of any tape recorded on any cassette deck. This piezo-electric system is actually a Philips technology adapted from a their system used by the Video2000 home video system. The inclusion of a dbx noise reduction system (beside Dolby B and C) guarantees high dynamic range recordings from Digital sources like the newly introduced CD. The mechanism used by this model is a standard 2-motor Direct Drive model with single capstan transport. If all this was not enough there were also 2 versions of this model. This time however is a simple aesthetic difference where the international model was silver(gold) while the Japanese market model was black and it also had a black stripe at the bottom of the front making-it look taller.   

Technical Data:
Head: 3-Head System - Sendust (no Monitor) 
Motors: 2 motor Direct Drive
dbx, Dolby B-C, Automatic Compu-Bias, separate wired remote RMC-1
Frequency Response: 20Hz to 22kHz (Metal tape)
    20Hz to 20kHz (Chrome)
    20Hz to 20kHz (Normal)
Wow and Flutter: 0,025% (WRMS)
Dimensions (WxHxD): 416x122x300mm
Weight: 6.5kg
Available in black and silver(gold).
