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.

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.

The discerning shopper will recognize ia at once as a sensible component for fine music systems. To be sure, there will be many music lovers who will purchase the GT15 because of its surprisingly low price. These buyers are in for a pleasant surprise. Their modest investment will return pleasurable, high performance dividends for years to come.

 

The tonearm

It weighs a remarkable 10 grams. And this ultra-low mass arm rides on jewel bearings to ensure low friction, faultless tracking. Stylus pressure is set by an adjustable calibrated counterweight. The GT15 tonearm tracks effortlessly, even across a warped record, because its low mass enables it to respond readily to abrupt vertical motions. Remember, the greater the mass of a tonearm, the harder it is to stop its motion and reverse it.

 

The motor

Another version of the time-tested, dependable Garrard Synchro-Lab unit. Just as in the higher priced GT25, the motor consists of two sections. One section starts platter rotation with a powerful thrust the moment the "start" control is used. The other section maintains absolutely steady speed despite the changes always taking place in your voltage supply at home.

 

 

The platter

Heavy lathe-turned aluminum for uniform density and balance. The platter is isolated from the motor by a precision-ground flexible belt.

 

The controls

Like all the models in the GT series, GT15 provides manual single play, automatic single play, automatic multiple play and automatic repeat play. Its controls are sensibly grouped and easy to operate - the feather touch "start" button is just one example.

The belt-driven GT15 employs the patented Delglide Automatic System, gentle cueing, two point record support, precise anti-skating control and a hand some base and hinged dust cover. Its reliability is underscored by a 3 year limited warranty including parts and labor. It's good turntable to start with, and as your music system grows in sophistication you'll find it's a good one to stay with.

Garrard GT12 turntable

The GT12 turntable is an excellent example of performance, features and reliability at a cost which can only be described as a astonishingly low.

 

The tonearm

It is critical that a cartridge be housed in a low mass tonearm so that the stylus can freely trace the complex signals in the record groove with accuracy. The S-shaped, gimbal supported tonearm has an incredibly low mass of 7 grams. On other comparably priced turntable approaches this remarkable specification.

The GT12 is available with a high quality , factory installed magnetic cartridge, or your dealer can recommend one based on your individual listening preferences.

 

The motor

Garrard tested many motor designs before selecting the 4-pole induction unit incorporated in the GT12. its characteristics include low vibration, high torque and steady speed. Moreover, the entire motor is isolated from the chassis by special rubber bushings to further reduce the possibility of vibration in any critical area involving record play.

 

The platter

The gracefully tapered platter is designed like those on many professional turntables. It is constructed of heavy duty steel, effectively shielding the cartridge from stray hum fields. The platter is rotated by a precision-ground belt, isolating it from any possible motor vibrations. The result is specifications that clearly stamp the GT12 as a turntable capable of true high fidelity sound reproduction.

 

Delglide and more

The GT12 incorporates the Delglide system for full automation, the very same system employed in Garrard's most expensive models. It is quiet, smooth and utterly reliable. With Delglide, your records are handled with the gentleness they deserve. Located directly under the tonearm, it eliminates cumbersome linkages, and controls the tonearm by efficient, precise rotary action.

The GT12 also incorporates a damped cueing control precise anti-skating and a handsome base and dust cover.

As quiet a performer as your're likely to find in a moderately-priced turntable, the PL-117D owes much of its outstanding operation features to the use of a high-torque 4-pole synchronous motor and to its howling-free, hand-crafted cabinet. These important design features, coupled with a sensitive S-shaped pipe-arm with anti-skating device, ensure that the PL-117D will deliver the finest of performance specifications - wow and flutter of only 0,07% (WRMS) and a very high Signal-to-Noise Ratio of 63 dB (DIN B). Beautifully constructed, the PL-117D is a perfect addition to a new system of stereo components that is designed on the basis of tonal quality.

 

Belt-Drive system with 4-pole synchronous motor

The strong turntable platter, free from fluctuation in line voltage and load, is rotated by a high-torque precision 4-pole synchronous motor and its polished polyurethane belt. These turntable features contribute to wow and flutter of 0,07% (WRMS) and high Signal-to-Noise Ratio of 63 dB (DIN B)

 

Sensitive S-shaped pipe-arm with anti-skating device

An angular-contact bearing is employed at the revolving point of the tonearm's ball-bearing which ensures that the precision tonearm and its easy-to-operate anti-skating device can trace record grooves faithfully during playback, either vertically or horizontally, with even light stylus pressure cartridges. The turntable is also complete with a direct-readout stylus pressure counterweight for easy replacement of cartridges.

 

Convenient cueing device

The viscous-damped cueing device is connected to the arm elevation lever to help prevent damage to both stylus and records often caused by misoperation.

 

Howling-free, Double floating system for superior tonal quality.

The cabinet of the PL-117D is strong, howling-free and typical of quality Pioneer craftsmanship. Its solid surface panel features such excellent properties as optimum inner loss, impregnable strength and high density. It is thus free from resonance. The turntable platter and tonearm are fixed to the  chassis of the PL-117D, suspended from the surface panel with springs. The motor is fixed to the surface panel with a rubber cushion. Further improvements that contribute to outstanding tonal quality and exact record reproduction are the insulators composed of butyl rubber and natural rubber which prevent vibration conveyed from the floors. The cabinet itself is elegantly styled in an attractive walnut grain finish.
