Sansui SR-535 turntable

Automatic Direct-Drive Turntable

Sansui wants everyone to enjoy hi-fi music with the minimum possible noise, distortion and inconvenience. That's why the Sansui SR-535 automatic direct-drive turntable puts the emphasis on pure hi-fi performance and true handling ease. Accuracy of platter rotation, and a strong, anti-howl construction characteristics in the musical department. The direct-drive motor is a high-torque type and the special tonearm has a unique support to ensure delicate performance. Record reproduction is always clean and pure.

One simple control, the Auto/Manual Play Lever, does all the work. Put a record on the platter, set the record-size selector and pull the lever once; the tonearm is lifted, moved and gently lowered to the lead-in groove, when the record ends, the arm is returned to its rest and power shuts off automatically. The same lever permits manual play when desired. More convenience is offered in the Repeat facility permitting you to select one to five replays, or infinite replay.

 

Automatic Operation

One control knob does it all. The jumbo-sized Auto/Manual Play Lever has three positions of Manual On, Off, Auto Start/Stop. For a single automatic play, you simply place a record on the platter and gently pull the Auto/Manual lever into the Auto Start/Stop position. The tonearm lifts automatically as the platter begins to spin, the stylus is placed over the lead-in groove of the record, and the tonearm descends to begin play. If you desire to interrupt play at any time, simply pull the lever again, or you may wait till the record ends. In either case, the arm is automatically lifted  and returned to its rest, and power is switched off, all without your assistance.

When manual play is desired, simply set the control lever to the Manual On position. When the platter begins to rotate, move the stylus to over the part of the record you want to hear. An oil-damped Cueing Lever is provided to help you avoid damaging your valuable records. As in Auto Play, the Manual position on the lever allows the automatic return mechanism to return the tonearm to its rest.

Additional convenience Auto Repeat control on the SR-535.

In the Off position if sets the turntable in auto-return mode. Or, you can select from "1" to "5" repeat plays, or "infinite" which allows the automatic mechanism to continuously repeat its simple job until you change the repeat control settings.

 

Accurate Drive System

Sansui engineers have done if again. The platter of the Sr-535 never shows any appreciable slow-down under reasonable loads. This means that your 33-⅓ and 45 rpm records are always played at the correct speeds for best musical performance. This accuracy is assured by an advanced, high-torque, 20-pole/30-slot brushless DC type servo motor for direct drive. Speed drift is effectively eliminated by the Sansui-exclusive rotor position sensor mechanism, coupled with the motor's bias-controlled saturable core (Sansui Pat. Pend). Thanks to the dependable power supply, the drive voltage is kept constant for accuracy under any conditions.

Mechanically, as well as electrically, the SR-535 has impressive precision. All components and parts are designed, machined and assembled under very careful super-vision to live up to Sansui's strict quality control standards. The bearing sleeve is mirror finished for complete roundness, for instance. The motor shaft/center spindle is formed of the finest polished carbon-chrome steel and rides in a thrust bearing of tough friction-resisting synthetic polyamide. We've used a special lubricant, one developed by the aerospace industry, to ensure low friction in the motor over long years of operation.

Smoother rotation is also ensured by the heavy (1,4 kg ) aluminum die-cast platter. This, plus Sansui's attention to every minor point in design and construction, gives the Sr-535 impressive specifications low 0,038% wo/flutter and better than 67 dB rumble.

Fine speed adjustment with strobe

On the edge of the oversized (31,8 cm or just over 12-inch) platter there are four rows of stroboscopic patterns, two each for both speeds to permit fine adjustment when your electrical power is either 50 Hz or 60 Hz. The strobe light illuminates the platter edge so that you can visually check its rotation speed for accuracy. Once the correct speed is reached, the speeds will continue to spin accurately, or you can use two fine speed controls to vary platter by as much as ±3,5% from the standard speeds. By the way, these controls are recessed to avoid accidental speed change.

 

Stabilized Tonearm

Exceptionally high tonearm stability is one of the reasons the Sansui Sr-535 performs with such high musicality. Despite the attractive price of this fully automatic turntable, the tonearm has the same stability and resistance to resonance found in much more expensive models. Spurious vertical travel and harmful torsion or twisting are avoided by a special support with two vertical pivots. The mass of the arm is concentrated at these points to clearly define the unit's fulcrum for better mechanical advantages, particularly in the bass frequencies which are delivered from your record free of "mud".

Low-resonance design

Resonance is further suppressed by the special acoustic absorbent, we use inside the highly rigid tonearm tubing. Then, we've decoupled the balance weight from the arm shaft vis a newly designed rubber damper. All types of vibration whether  transmitted through the air or through the physical structure, are shut out before reach the stylus.

Other tonearm features:

Zinc-alloy die-cast arm base; a massive heavy structure to improve bass response by firmly securing the arm to the cabinet.

Direct readout tracking force dial; precision-calibrated markings every 0,25grams one rotation covers 0-to-3 gram range

Gold-plated connection pins; free from all forms of rust to ensure maximum transfer of the tiny electrical signals from cartridge to your amplifier

Arm lifter lever; oil damped for smooth operation

Anti-skate knob; adjustable even as the record is played, another bonus in this attractively priced turntable.

 

Cabinet

Sansui designers take special pride in the clean, modernistic looks of the SR-535 turntable. The silver metallic finish sets off the precision lines of the cabinet and is just "flat" enough to resist glare from room lights without appearing too dull. The clean lines are more than good looking, advanced computer technology and time-tested carpentry techniques alike were used in designing the Sr-535 to resist acoustic feedback or "howling". The automatic mechanism is mounted on a separate chassis inside the cabinet for instance while the low-profile of the base and its complex suspension system further ensure good sound.

Complex-suspension

To defeat all types of vibration before they can harm your music, the SR-535 is suspended in a complex system of rubber and spring devices. Air-borne vibration, such as sound-waves from your speakers, and structure-borne vibrations, such as originating from your operation of amplifier or receiver controls, from footsteps, etc. Are effectively damped so that your music retains its tight bass, clean mids and crisp highs.

Phase Linear 8000 turntable

Model 8000 Series Two Linear Motor Turntable

No other turntable can match the Phase 8000, because no other turntable has such advanced motors. You can't buy a quieter turntable. Or one with as low wow and flutter. Or one that tracks better.

The Phase 8000's tangential tracking tone arm keeps the stylus in perfect 90° tangent with the grooves. It's the same way the master disc was cut, so the motion of your stylus is identical to the cutterhead stylus. There's absolutely no tracking distortion. No crosstalk. No skating force that can actually re-cut your grooves.

 

New Linear Motor Eliminates Mechanical Linkage

Other manufacturers have tried to move tangential tone arms with worm gears. Belts. Rollers. All with the same sad result; Mechanical connections pass on the noise and vibration of the motor. The Phase 8000 solves this problem with an ingenious Linear Motor. The tone arm base is a permanently magnetized armature that glides along guide bars above electro-magnetic coils. The arm moves by direct induction - not mechanical connection. So there's virtually no noise. Inside the tonearm, an opto-electric detector cell senses the slightest tracking error, and instantly sends correcting signals to keep the arm on track.

Garrard GT-25 turntable

Features for feature, dollar for dollar the GT25 is superior to any turntable in its price range. The GT25 provides music reproduction on a par with the more expensive GT35 and incorporates many of the same features.

Yet, the GT25 costs no more than many of the manual turntables on the market today. The GT25 is an ideal component for the music lover who insists on performance without compromise, plus the safety and convenience of fully automatic operation - at a price that is economical.

The tonearm

The tiny stylus, as it traces the groove , must bear the weight of the tonearm. It is of critical importance that the weight of the tonearm be held to a minimum. The GT25's nine inch, tubular aluminum tonearm with magnesium headshell, weighs just 12 grams. It rides on the same low friction jewel bearings as the GT35. it will readily track records that are badly warped - something tonearms of higher mass simply can't do.

 

 

The motor

An advanced development of Garrard's time tested Synchro-Lab unit it combines an induction rotor for high starting torque and a synchronous section locked to the 60 sycle frequency of the power line. accurate speed is assured even when the voltage fluctuates. The precision bearings are of sintered bronze and are oil retaining. The entire motor is isolated from the turntable by special rubber bushings, ensuring freedom from vibration.

The platter

Die cast if the same special aluminum alloy as in the GT35, the platter is rotated by a precision-ground belt, isolating it from the motor . The platter is balanced and diamond turned during manufacture to achieve true concentric trim. These materials and manufacturing processes help to explain the excellent rumble, wow and flutter specifications of the GT25.

A 12 gram tonearm. The advanced Sychro-Lab motor A die-cast platter. A two points record support. The Delglide Automatic System. A specially designed base and dust cover. An unprecedented 3 year limited warranty including parts and labor. There are turntables in its price range that offer some of the features and specification of the GT25. the GT25 has them all at a price that makes it a best buy.

Garrard GT-35 turntable

The GT35 is a perfect example of meticulous engineering. Everything about it - its impressive rumble, wow and flutter specifications, its low tonearm mass and low bearing friction - confirm the visual and tactile impressions you get of high performance.

The tonearm

Garrard engineering has given special attention to this critical aspect of record play. The tonearm of the GT35 weighs just 12 grams, lower than any automatic turntable in its price range. The tonearm features an ultra-light magnesium headshell and jewel bearings ensure that the finest and lightest tracking cartridges will perform up to their maximum capability.

The motor

A DC servo-controlled unit incorporating electronic sub circuits in a self-correcting network. Rumble, wow and flutter specifications rival the finest turntables, including the expensive direct drive units. The GT35 motor rotates records at rock-steady speed with total freedom from AC vibration.

The platter

Dynamically balanced and die-cast from a special aluminum alloy, assuring uniform density. It is rotated by a precision-ground flexible belt, further reducing vibration. The GT35 specifications are well within the professional transcription category.

 

 

Variable speed

Electronic control with independent adjustments for 33-⅓ and 45 rpm. Correct speed is monitored by a stroboscope cast into the periphery of the platter. It is illuminated by an LED ( rather than the usual neon) resulting in a distinct image easily read, even in a brightly lit room.

Base and dust cover

Both the glass filled polyester  upper section and lower wooden section of the base form a barrier against vibration and resonance. Special shock absorbent feet minimize acoustic feedback. The dust cover pivots freely and can be raised and lowered even while a record is being played.

The Delglide Automatic System in the GT35 offers unerring accuracy and silent and sure operation. The combination of measured performance and features achieves the goal of its designers totally gratifying music reproduction.

Garrard GT-55 turntable

Generation Two Turntable with True Tangent Tracking

 

Since the first flat disc record was made, just about many year ago, audio engineers have been searching for a way to eliminate tracking error.

The master record is cut with a stylus that maintains a constant 90° tangent to the groove it is inscribing. Problem: play it back the same way . Anything else produces tracking error (maybe a little, maybe a fair amount), and that means distortion. In many years of search, turntable manufacturers have proposed an array of solutions. Some have been inventive, even ingenious; other have verged on the ridiculous. None until guide recently have been successful. Now there are there; all as different from any other turntable as the flat disc is from Edison's cylinder. Two of them solve the problem by a radical departure from traditional design; they move the entire tonearm across the record - pivot, counterweight and all.

Ingenious, Complex. And expensive.

Garrard found another way. Our half-century of turntable engineering culminated in a solution that retains the pivoted tonearm yet keeps the stylus in an absolutely true 90° tangent to the groove at every point from the record's outer rim right to the label.

Further, we did this with a computer-designed tonearm made of the ultimate in lightweight, rigid metals; magnesium. It has the lowest mass (14 grams) - and the lowest inertial drag - of any multiple-play turntable. And it is automatic. Fully automatic. Silky-smooth, silently automatic, and therefore gentler and safer than the steadiest hand, whether you use it as a single play or a multiple play turntable.

Garrard's solution - the GT55 - delivers other advantages, as well. Some small, some quite large, depending on what's important to you.

And one overriding advantage. The others sell for prices up to $700. the GT55 is under $250. which makes True Tracking not a costly privilege but an available benefit. To everybody.

 

True Tangent Tonearm

The computer designed True Tangent Tonearm keeps the stylus at a constant 90°  tangent to the record groove, by means of an articulated head. The angle between the head (holding cartridge and stylus) and the shaft of the tonearm changes with each groove. Thus, while the tonearm swings in an are over the record, the stylus is kept at a constant, true tangent. Tracking error is eliminated, with its consequent problems of record wear and harmonic distortion.

Tonearm

Made of modern, low-mass magnesium, the GT55'stonearm weight an astonishing 14 grams. It rides on jewel vertical pivots and horizontal ball bearings. Inertial drag and friction are reduced to absolute minimum levels.

Anti-skating protection on the GT55 is provided by a unique, patented system. Completely non-mechanical, it operates magnetically, and varies in proportion to the actual skating force across the surface of the disc. It is calibrated for elliptical and CD4 styli.

Cueing rate is variable, and the cueing operation is damped in both directions by the main cam of the turntable

 

The GT55 is the only belt-drive multiple play turntable with a DC servo motor. Both the motor and the belt-driven automatic mechanism are completely new. The speed of the motor is continuously governed and regulated by an electronic servo system. The automatic mechanism is smooth and silent in both single and multiple play. It is also completely disengaged from the tone arm when the record is playing.

Speed control is variable ±3%, and is electronically governed by the servo which controls the motor. Read-out monitored by an illuminated stroboscope.

The platter is four pounds, die-cast and dynamically balanced for smooth, precise rotation. It is driven by a flexible belt, which insulates it from any possible motor vibration.

The precision controls are conveniently grouped , and include selectors for single or multiple play, as well as a repeat-play option for use in either mode.

Elac Miracord 50H mkII turntable

At first glance, most automatic changers seem pretty much the same. A record drops, the turntable spins, a tone arm moves over to the record, where a stylus ( or needle) drops into the grooves. This sets off a chain of electronic impulses that ends up as music from your speakers. Any automatic changer will do all this.

An Elac Miracord will do it better. Every step of the way. Result; a fuller, richer sound from your records. In very simple terms, here's how we do it:

Start with the Elac tone arm. Its job is to hold the cartridge (which holds the stylus) and swing out onto the record. Most tone arms will do just that. The ones we build do just a litle more.

 to begin with, there's the tracking force. This is technical talk for the amount of pressure the tone arm brings down on your records. Naturally, the lighter the pressure, the lower the friction - and the more plays you'll get from each record and each stylus. That's why at  the base of the Elac tone arm you'll find a special little knob that lets you adjust the weight coming down on your records to less than one gram - or one twenty-eight of an ounce.

How many times have you tried to play a specific cut on an LP and dropped the tone arm either past the beginning of the tune either past the beginning of the tune you want, or into the ending of the song before it.

 

That can be hard on your ears, and even harder on your records. That's why we've come up with a cueing device so foolproof you can literally pick any groove on a record and ease the needle into it. Just flip a lever which gently raises the tone arm and lets it float with the stylus a hair's breadth over the record. Position the arm exactly where you want it, and flip the lever back. This operates a cleverly-designed, tiny piston which softly lowers the needle into the gtoove you've selected.

Which brings us to yet another example of Elac wizardry. The natural inclination for a needle on a record is to wear against the inside wall of each groove, (if you've ever heard a stereo record where the separation seems poor or the sound is distorted, this could well be the cause), Elac eliminates this inward drag with a special anti-skate device.

All Elac changers have push-button controls, positioned where they;re easiest to reach.

Everything is controlled by push-buttons, including the heavy-duty motor. Bearings are precision-made so you can forget about the annoyance of rumble and flutter. And life-time lubricants help keep maintenance to the barest minimum.

Everything we've mentioned so far is on every Elac Miracord. An impressive set of credits, to be sure. For some models, however like the 50H mkII its just the beginning.

 

Quite simply, the best automatic turntable money will buy. The 50H mkII contains a set of advantages that places it beyond the reach of any other charger in the world. With the variable speed control you can set the speed at precisely 33-⅓ or precisely 45 rpm, and a stroboscopic ring on the turntable will read out the accuracy of the speed. You may vary the speed by as much as three per cent either way. This not only assures you of exact control for normal listening, but also comes in handy for special uses such as dubbing sound home movies, or playing along with a musical instrument, where precise pitch is essential.

The 50H mkII is also a rarity in that you can now play your finest records and the precision arm will be lowered by the silicon damped cueing device, even in the automatic phase. A newly developed synchronous hysteresis motor reduces rumble to  an all-time low while maintaining a speed accuracy that is truly incredible. All told, the Elac Miracord 50H mkII represents the ultimate in automatic changers but to fully appreciate everything it offers you've really got to hear it for yourself.

Sansui FR-4060 turntable

Electronic Automatic Transcription Turntable

Stereo purists who still claim only a manually-operated turntable can faithfully reproduce disc recordings without strain have some catching up to do. For here is a turntable - a fully automated transcription turntable - which performs with the ease and stress-free operation of a first-class manual but has the convenience and practicality of an automatic as well. The Sansui FR-4060 very efficiently eliminates the one major disadvantage of the complicated :changer-type" turntable by employing a non-mechanical, purely electric device, the galvano-magnetic detection mechanism, to detect the end of a record and prepare the tonearm for automatic operation. It makes it possible for the tonearm to ride completely free of stress-producing mechanical linkage systems until it is time for the automatic lead-in, return, repeat or cut operations to take over. In this way, the stylus is protected from distortion-producing lateral thrust, your records are safeguarded just as they would be on a manual, and since the tonearm is free, it can be moved to any part of the record manually, even during automatic play.

 

 

The Frequency Response-4060 features an unusually sensitive S-shaped tonearm, a newly developed Sansui SV27 magnetic cartridge with superb tonal characteristics, a special low-capacitance output cable, floating-mount base and platter design and many other original Sansui quality details. It is also fitted with a connection socket for the Sansui SRC-6 control unit (optional) for full remote-control of all automatic functions.

Those stereo purists who maintain that a manual turntable is the epitome of perfection have only to check out the FR-4060. by adding the convenience of automatic operation to one of the finest precision manuals ever created. Sansui has come up with a turntable to fully satisfy your specific needs.
