The Tuner captures the radio waves from the air. There are two kinds of radio transmission: AM and FM. Most ordinary table radios receive AM only. FM is a newer form of static-free radio broadcasting being used to transmit many good music programs. FM stations can broadcast either stereo or monophonic programs. You can buy either an FM tuner, an FM stereo tuner, or an AM-FM tuner depending on your needs.

The Turntable is a precision piece of equipment, made as carefully as a fine watch. Associated with the turntable is the arm and pick-up cartridge. The cartridge holds the diamond phonograph stylus and transforms the movement of the stylus in the record groove to electrical signals. Record changers are sometimes used instead of turntables, although in a true high fidelity system the turntable is preferred.

The Amplifier is the link between the tuner or turntable and the speakers. The amplifier strengthens the minute signals fed into it by the tuner, tape recorder or record player and turns these signals into electrical impulses strong enough to drive the speakers. It is with the amplifier that you control the sound ... make it louder or softer ... or change the tonal balance to suit your ears.

The Speaker. It is here that the carefully controlled electrical signal is changed into sound waves you can hear. The speaker and its enclosure are ideally purchased as an integral unit. The enclosure is as important to the speaker as the sounding board is to the strings of a piano.

Component stereo is actually "Custom Stereo." Because components are separate units, you can choose the parts you want and need to fit your budget and your room. These compact electronic units fit anywhere, even in rooms where you might think that installation of a fine stereo system is improbable.

Attractive slip-on cases are designed to fit all H. H. Scott components, which are so handsome in themselves they can be placed anywhere right in these cases.

H. H. Scott components can be placed in furniture you already own, on tables or in bookshelves. They can be used in cabinets designed especially for components, in standard furniture simply adapted to components, or custom-installed in walls, doors or panelling.

There is a wide selection of furniture, made specifically fo. stereo components, available from the same dealer who supplies you with the components themselves. These cabinets come in a variety of sizes and finishes, usually with space for a record player, amplifier, and a tape recorder. Record storage space is provided in many of the cabinets, or in matching cabinets that hold hundreds of stereo records. Installation is a matter of minutes, and you have a handsome unit blending perfectly with the feeling and decor of your rooms.

The growth of the high fidelity industry has brought with it specialists in the decorating field who are also trained in audio installations. More and more people are consulting decorators to design and construct music systems in their homes. In most cases these systems are built into the wall and concealed by wood panelling. Special units can be designed to house any combination of equipment (high fidelity system with speakers, record storage, tape recorder, etc.). Only one simple cut-out is required to panel mount an H. H. Scott component.

Purchasing Scott Stereo Components is easy. There are more than 500 franchised H. H. Scott dealer showrooms across America. Audio specialists at these showrooms will be glad to demonstrate Scott components for you, and help you select those best suiting your needs.

Installation is simple. You can do it yourself, or your H. H. Scott dealer will install your system for you at modest cost.

Scott components are easy to use. The panels are marked with small dots showing typical knob settings, so any member of your family can play your system. Many Scott components come with a convenient "Photo-Guide." Even without these special helps, you can learn to use H. H. Scott components in a short time.

The listener needs only an FM tuner equipped for multiplex (like the Scott 350) or an FM tuner together with a multiplex adaptor, plus the usual accoutrements of stereo (a dual channel amplifier and two speakers). Operation is not complex. You just tune to one station as you do now for regular FM broadcasts, and you hear true stereophonic sound with all the advantages of FM - freedom from noise, interference and distortion.

Humans are capable of hearing sounds between about 20 and 20,000 cycles per second. Any sound above 20,000 cycles per second is referred to as "supersonic" because it is above the range of human hearing.

Most good FM tuners are capable of reproducing these supersonic frequencies above 20,000 cycles per second ("cps" for short). Though you cannot hear them, these supersonic frequencies are used very effectively for multiplex. At a frequency of 38,000 cycles per seeond (cps), high above the sounds you can hear, the second (stereo information) signal is added on. While you can't hear this second signal, your FM tuner can, and, if equipped for multiplex, will convert this into sound you can hear - stereo sound.

This second signal is not either the left or right channel. If it were, a listener with a monophonic tuner would hear only half of the program. Instead (see diagram below), a method is used that provides the full monophonic signal (left plus right) for the listener with a regular FM tuner, and stereo for the listener with multiplex equipment.

The stereo quality depends on how well the multiplex tuner handles the second signal (stereo information). If very little of the second signal is being properly processed, there will be poor stereo quality (poor separation between the left and right channels). Simply having sound from both speakers does not necessarily mean you have stereo.

Conventional narrow-band tuners cannot give the fine stereo quality obtained with Scott Wide-Band tuners. As the FCC pointed out, the approved multiplex stereo system "... like any multiplex transmission system, will increase energy transmission at the edges of the channel involved. Accordingly for optimum stereophonic reception, the (tuners) bandwidth ... must be considerably greater than that of monophonic (tuners)...."* Scott tuners have always had the wider IF bandwidth needed. Therefore, if you now own a Scott tuner, adding a 335 or LM-35 adaptor to your system will give you outstanding stereo separation matching the FCC transmission specifications.
.

Since stereo FM broadcasts are such an abundant source of high quality program material, many listeners will want to make off-the-air stereo tape recordings. In many instances, however, conventional multiplex circuitry causes interference with a tape recorder, resulting in whistles and beeps being recorded on the tape. Scott multiplex units incorporate the expensive filters needed to prevent this interference. Scott equipment can be used with any tape recorder.

New FM Stereo will bring you thrilling broadcasts of world famous symphony orchestras and opera companies ... intimate close-ups of jazz in stereo ... dramatic presentations with life-like movement. You will hear the wonderful new sound of FM multiplex stereo in your home ... and using Scott equipment, you will be able to make flawless off-the-air stereo tape recordings.

High Fidelity tested the LT-10 and reported on it in their April 1961 issue. They found it the most sensitive tuner ever tested by IHFM standards. In their equipment review they stated that the LT-10 "... sounds as good as it measures, and that is the highest compliment one can pay."
High Fidelity Magazine

"... No effort has been spared to make the building job simple, a lot of fun, and yet have the builder end up with a unit that looks and works like factory-built equipment . . . Whizzed through the complete construction (of the LK-72) in only about 11 1/2 hours. A conservatively designed, versatile integrated stereo amplifier that should be a pleasure to build
and a pleasure to use."
Electronics World

"... It took us less than 7 hours to put (the LT-10) together and that includes alignment. ... Without hesitation we would recommend the H. H. Scott LT-10 FM Tuner Kit to the beginner as well as the more experienced Audiofan. ... Surely only the most sophisticated engineering thinking could design a kit as simple and foolproof as this one is. "
Audio Magazine

Electronics Illustrated in a project designed to construct and test every FM tuner kit available reported the LT-10 was "the most sensitive ... tuner" tested.

.

This exceptional preamplifier kit has every feature you'll ever need or want. It is so perfectly designed that distortion is below the limits of even the finest test equipment, and cannot be accurately measured. Hum is completely inaudible even in the magnetic positions due to the all-aluminum chassis, shielded power supply, and DC heated tubes. The LC-21 can be used for laboratory applications where frequency response below 10 cps is desired. Among the 16 front panel controls are complete tape monitor switching facilities, front panel derived center channel level control, and phase reverse switch. The LC-21 is an ideal companion to the LK-150 stereo power amplifier kit.

The IHFM power band of this 130 (65/65) watt unit goes beyond the 19 to 25,000 cps range of available test equipment. Conservatively engineered, the highly efficient design of the LK-150's powerful output transformers will typically provide 80 watts (IHFM) output on each channel at 20 cps - where the power is really needed. Famed matched 6550 output tubes - rated at 100 watts - are used well below manufacturer's ratings to assure long operating life. Switchable subsonic filter permits the use of the LK-150 for laboratory applications where response below 5 cps is required. Input sensitivity is switchable between 2.5 volts (for the LC-21 and other Scott preamplifiers) and 1.5 volts for preamplifiers with lower output.

The LT-10, introduced just one year ago, has single-handedly changed the hitherto common impression that it was impossible to build a good FM tuner kit. High Fidelity Magazine buiit and tested an LT-10. They found it the most sensitive tuner ever checked for IHFM sensitivity, either kit or wired, regardless of price. Nominally rated at 2.2 microvolts iHFM sensitivity, LT-10s typically provide even more sensitive performance (High Fidelity found 1.4uv). This sensitive FM tuner can be used with either the LM-35 Wide-Band adaptor kit or 335 Wide-Band adaptor to receive FM stereo broadcasts.

An amplifier's ability to perform properly depends on how much power it can produce over the entire audible spectrum. The very low frequencies, below 50 cps, require more power than the higher frequencies. Until recently, manufacturers designated output at one frequency, 1000 cps. This method was unsatisfactory because an amplifier with 25 watts output at 1000 cycles might have much lower output in the important frequency range between 20 and 50 cps. To provide a more meaningful guide to an amplifier's performance, the Institute of High Fidelity Manufacturers (IHFM) adopted the "power band" method of rating. The "power band" is the frequency range over which the amplifier delivers half power at its rated distortion. It is a meaningful guide to performance throughout the entire audio range. All Scott amplifier specifications include the IHFM Power Band rating.

Scott applies a more rigorous requirement to all its amplifiers - they must deliver at least full rated power from 20 to 20,000 cps, and they must have additional reserve power at the critical low frequencies. This is why you can be sure that the power ratings of Scott amplifiers show their minimum - not maximum - output.

The price differential between the various H. H. Scott amplifiers reflects only differences in power and operating features. There is only one quality in any H. H. Scott amplifier, and this is the best quality possible at this stage of the art. To choose an amplifier, thoroughly check all features of each model to make sure that the one you select has those provisions and controls you desire. Selecting an amplifier that supplies sufficient power for your listening conditions is also important.

Four factors are involved in selecting the proper power rating:
.

• (1) The efficiency of your speaker system. Some systems need more power than others for the same room volume. A speaker's efficiency, however, is absolutely no criterion of its quality.
• (2) The size of the listening room, and the absence or presence of sound absorbing materials such as rugs and drapes. Large rooms require more power.
• (3) How loudly or softly you ordinarily play your music.
• (4) You need more power if you want to place extension speakers in other rooms, since additional speakers require more power.

.
If all these factors indicate the desirability of higher power, then you should consider an amplifier such as the 72-watt 299C or 100-watt 296. On the other hand, if factors point toward lower power, then the 48-watt 222C should be considered.

To help keep hum and noise inaudible, Scott uses non-magnetic electrolytic aluminum chassis. Most manufacturers use ordinary steel, which is far less satisfactory. The aluminum chassis also facilitates heat dissipation. All Scott preamplifier tube heaters use direct current, which also helps to reduce hum and noise. Long operating life is assured by conservatively rated parts, operated well below their ratings. A special subsonic (below 20 cps) sharp cutoff filter prevents power waste due to sub-audible rumble, eccentric records, or acoustic feedback.

FM stereo (multiplex) makes more severe demands of a tuner than regular monophonic reception. Before you purchase an FM tuner, an understanding of the factors involved in good tuner design will help you make the most intelligent investment.

Usable sensitivity - measures a tuner's ability to receive weak signals with very low hum, noise and distortion. Scott's high usable sensitivity is in part due to the silver-plated front end on all Scott tuners. Silver's high conductivity preserv.es the full quality of even the weakest signals without introducing the noise, hum or distortion of conventional tuners.

Selectivity - is the ability to completely separate stations on nearby channels. Scott's Wide-Band IF's most closely approach the ideal by amplifying the desired signal and completely rejecting all nearby stations. Scott tuners separate stations that conventional narrow-band tuners would pass by.

Freedom from drift - A tuner must stay on station without wandering (or drifting). Narrow-band tuners use undesirable automatic frequency control (AFC) to prevent drifting. AFC introduces considerable distortion and reduces bass response. AFC also reduces selectivity because its magnet-like attraction towards stronger stations pulls away from nearby weak ones. Scott tuners utilize Wide-Band design rather than AFC to eliminate drift, bringing you the full range broadcast without introducing distortion.

Stereo separation with low distortion - a must for good FM stereo reception. Conventional narrow-band tuners inherently cannot give as fine stereo quality as Wide-Band tuners. When you select your tuner, be sure to hear a Scott Wide-Band tuner so you can hear the difference before you invest.

Special circuitry for flawless tape recording - Conventional tuners often cause whistles and beats because of interference with many tape recorders. Scott Wide-Band tuners do not interfere with any tape recorder, permitting you to build your own flawless stereo tape library.

If you wish to enjoy multiplex stereo reception, choose either the 350B Wide-Band FM Stereo Multiplex Tuner or the 4310 Professional FM Stereo Multiplex Broadcast Monitor. Both provide built-in multiplex circuitry which permits you to enjoy either stereophonic or monophonic FM broadcasts. The 4310, in addition, offers many remarkable features of great value to those desiring professional performance.

If, in addition, you desire AM, the 333 offers the same FM Multiplex circuitry as the 350B plus a separate Wide-Band AM section. If you do not desire multiplex at the present time, the 314 Wide-Band FM Tuner will provide excellent results. The addition of a 335 Multiplex Adaptor at a later date will convert the 314 for stereophonic reception. The 335 can be used with any Scott monophonic FM tuner.

For the kit builder desiring multiplex reception, the LT-lll Wide-Band FM stereo tuner kit (with pre-wired multiplex circuitry) is an ideal choice. If you already own an LT-10 Wide-Band FM tuner kit (monophonic performance of the LT-110 and LT-10 are identical), you can build an LM-35 multiplex adaptor kit which will give you the same stereo performance as an LT-110.
.

The model 355 and 208 include FM Multiplex Stereo, Wide-Range AM, a complete stereo control center and dual 40 watt power amplifier. The 208 Power Amplifier Section can be removed from the 355 as far as 50 feet away. The 340 offers FM Multiplex stereo, a versatile stereo control center and dual 30 watt stereo power amplifier all on one compact chassis. Those whose power requirements are less stringent, and who do not desire AM should choose the modestly priced 340.

Instruction books were written so that they avoided the pitfalls common to other kits. They were in full color. Only a limited number of steps were described per page, and special Part-Charts were created to hold the parts described on each page separately, and in the order used. The kit builder need know nothing about engineering to successfully build Scottkits.

Results have been spectacular. Amateurs who never even soldered before report that they have built Scottkits in just a few hours that beat our published specifications. Magazine editors and reviewers tell us our specifications are much too conservative. Other manufacturers are paying us the highest compliment of emulating our designs and original features.

There is one thing, however, that cannot be copied. The Scott reputation for quality, integrity and leadership ... a reputation hard-won by consistent attention to detail ... by continual advance in engineering ... by imaginative innovation ... by a philosophy that states "purchase by the customer marks a beginning ... not the end."

Our best salesmen are unpaid - our satisfied customers.
