Hermon Hosmer Scott
Hermon Hosmer Scott

Hermon Hosmer Scott founded H.H. Scott in 1947. The prefix H.H. was to differentiate his fledgling company from E. H. Scott, The Scott Radio Company of Chicago. Although H.H. is different than E.H., it is similar enough to make one wonder if perhaps Scott, always the shrewd businessman, hoped that some of E.H. Scotts’ reputation for quality might, by association, rub off onto his new company.

Mr. Scott invented the RC Oscillator, the selectively tuned RC circuit, various RC filters and the modern sweep circuit. He is perhaps best known for inventing the Dynaural Noise Suppressor, and held more than 100 patents (U.S. and foreign) for original research in the field of electronics. Early in his career, Mr. Scott worked on sound motion pictures and high-quality broadcast systems from 1929 to 1931 at Bell Telephone Laboratories, in New York, NY.

The company remained independent until 1973, when it was acquired by Electro Audio Dynamics of Europe. US operations were later relocated to Woburn, MA, offices. In 1985, the famous hi-fi brand was purchased and today operates as a division of Emerson Electronics. Hermon Hosmer Scott, died April 13,1975, in Lincoln, Massachusetts, after a long illness at the age of 66.

Stromberg-Carlson | USA

Stromberg-Carlson was a telecommunications equipment and electronics manufacturing company in the United States. It was formed in 1894 as a partnership by Alfred Stromberg and Androv Carlson. It was one of five companies that controlled the national supply of telephone equipment until after World War II. Stromberg-Carlson was originally located in Chicago, with Carlson managing manufacturing and Stromberg responsible for marketing. Stromberg-Carlson quickly established a reputation for reliable equipment and stable prices. The company also became involved in the broadcasting industry, acquiring WHAM, the oldest station in Rochester, and rebuilding it into a high power station; one of the first three FM broadcasting stations in the United States and possibly the oldest still in operation, now known as WBZA, dating from 1939.

Radio Craftsmen | USA

Radio Craftsman C500A
Radio Craftsman C500A

The Radio Craftsmen” seems to be founded in 1947 by John Cashman who before worked at Hallicrafters Radio Company. The first product (perhaps even before the official foundation of the company) is the very special designed kitchen radio “Kitchenaire”. Shown by SAMS Photofact in October 1946, this date is for sure. But the aim was to develop and produce home audio and television sets. Ed Miller and Sid Smith were two major engineers to work for Radio Craftsman during early 40’s – mid 50’s. Actually, Ed Miller is the founder of Sherwood and who leave Radio Craftsman before 1953 (This year he founded Sherwood and mainly focused on integrate amp and receiver). Sid Smith later left Radio Craftsman and joined Marantz as chief engineer in 1954.

Probably the famoust products are the Audio Amplifiers series 500: The first two generations of C500 were mostly engineered by Sid Smith and licensed by Western Electric. The first generation C500 was introduced in 1951. In 1952 the smooth corner version was replaced by the sharp corner version output. Radio Craftsman C500 is based on Williamson design which operates with 2 x KT66 output tube in triode but pure class A operation with 10 watt output. It has very natural, sweet, clear, realistic and transparent tone than many vintage and modern hi-fi amp.

Sherwood | Chicago | USA

Sherwood S-1000 II
Sherwood S-1000 II

Sherwood Electronic Labs was founded in Chicago in 1953 to manufacture an amplifier designed by legendary audio engineer Ed Miller. Determined to design high performance audio gear and to manufacture it themselves, Miller and his partner John Snow created a company that has long set the standard for audio excellence and efficient manufacturing.

Throughout the evolution of advanced audio electronics, Sherwood’s contributions have been invaluable. The world’s first commercial FM stereo broadcast employed Sherwood technology. Sherwood was the first to introduce digital readout tuners and computer-controlled tuners. And, most significantly, the industry’s first 100% all-silicon solid-state audio receiver came from Sherwood.

Sansui | Japanese HiFi Equipment

Sansui Electric Co., Ltd.  is a Japanese manufacturer of audio and video equipment. Founded in Tokyo in 1947, Sansui initially manufactured transformers, but by the 1960s had developed a reputation for making serious audio components. They were sold in foreign markets through that and the next decade. Sansui’s amplifiers and tuners from the 1960s and 1970s remain in demand by audio enthusiasts.

In 1971 Sansui introduced the Quadphonic Synthesizer QS-1, which could make simulated four channel stereo from two channel sources. Sansui developed the QS Regular Matrix system, which made it possible to transmit four channel Quadraphonic sound from a standard LP. The channel separation was only 3 dB, but because of the human way of hearing it sounded relatively good. In 1973 Sansui introduced the more advanced QS Vario Matrix decoder with 20 dB separation. Unfortunately the SQ system developed by Columbia/CBS was the most popular so called matrix system. But later QS decoders could also play SQ records. Some Sansui receivers could also play the most advanced four channel system – CD-4/Quadradisc by Japanese JVC and American RCA. Most big record companies used either SQ or CD-4, but Decca used the Sansui QS system.

Magnavox Amplifier | USA

In 1910 Magnavox started as “Commercial Wireless & Development Company” at Napa, California. Peter L. Jansen, Edwin S. Pridham (both ex Federal Telegraph Company) and Richard O’Connor (finance) formed the company to achieve a sensitive telephone receiver. In 1915 Jensen and Pridham have put a horn to their “telephone receiver with moving-coil system” and then used it as a “Fog-Horn” for the local baseball park (Radio & TV News, February 1959). They called it Magna Vox. They developed a phonograph pickup and made a joint venture with Sonora in 1917 called “Commercial Wireless & Development Company”. They developed the “SE4005 noise-cancelling microphone” for aircraft intercoms. In 1919 Magnavox moved from 526 Mission Street, San Francisco to 14th Street in Oakland and made vacuum-tube power amplifiers. In February 1920 Magnavox introduced a radio speaker, forerunner of the 1921 Model R-3. 1924 Magnavox began also to produce a tube “A” with a special design and a year later also radios.

Dynaco | High Quality Audio Components

Founded by David Hafler and Ed Laurent in Philadelphia, Pennsylvania in 1955, Dynaco was an American hi-fi audio system manufacturer popular in the 1960s and 1970s for its wide range of affordable, yet high quality audio components. In 1950, David Hafler and Herb Keroes started a Philadelphia-based company called Acrosound in order to build and sell audio-quality output transformers, primarily for home electronics hobbyists.[1] The two men refined and developed the Ultralinear audio circuit pioneered by British audio electronics engineer Alan Blumlein, using taps from the output transformer to feed signal back into the output stage screen grid circuitry.[1] The Acrosound transformer circuit was later used in many home-built and commercial hi-fi amplifiers in the early 1950s.[1] In order to appeal to a wider consumer market, Hafler decided to design and build entire power amplifiers as build-it-yourself kits, complete with preassembled, tested circuit boards that only required the customer to wire the boards to the transformers, controls, and power supply to complete the project.

Dynaco Dynakit Mark-IV
Dynaco Dynakit Mark-IV

Today, Dynaco is best remembered for its highly regarded vacuum tube stereo amplifier, the Stereo 70 (ST 70). Introduced in 1959, the ST 70 was available as a kit (Dynakit) intended for assembly by the purchaser or as a complete factory-wired unit. The ST 70 used four EL34 output tubes, one GZ34/5AR4 rectifier tube, two 7199 input (driver) tubes, two output transformers, one power transformer, and a preassembled printed circuit board (PCB) containing the driver circuit. It produced 35 watts per channel (wpc). The driver circuit had a single 7199 pentode/triode tube per channel, and used the driver tube to handle both voltage amplification and phase splitting. The output transformers are an ultralinear design, whereby part of the primary winding is fed back to the output tube’s screen grid. This design reduced distortion and improved audio quality.

A masterpiece of efficient circuit design, the ST 70 provided reliable, high-quality audio amplification at an affordable price. The popularity of the ST 70 contributed more than any other single product to continuing consumer interest in tube-based stereo amplifiers at a time of increasing market dominance by solid state audio products. Because of its excellent value for cost, Dynaco tube amplifiers were often referred to as “the poor man’s McIntosh.” More than 350,000 ST-70 amplifiers had been sold when production finally ceased, making the ST 70 the most popular tube power amplifier ever made.

McIntosh Collectors Amplifier | USA

McIntosh was originally founded in Silver Springs, Maryland, 1949. The vision of Frank McIntosh to build a better amplifier challenged what was believed possible. Gordon Gow and McIntosh, together designed the famous ‘Unity Coupled Circuit’. In 1950 the company launched the first preamplifier AE1. This was the first of many products beyond power amplifiers. With a polished brass faceplate and lacquered wood cabinet the C8 Preamplifier demonstrated the importance of industrial design. Switches allowed proper playback of LP records. In 1954, MC60 shown and MC30 amplifiers established the chrome chassis as a featured McIntosh design element. Today’s contemporary products use Polished Stainless Steel. In 1969, McIntosh Amplifiers power Woodstock, a pivotal moment in music history. Three days of peace, love and music for the hundreds of thousands who attended.

H.J. Leak & Co | in High Fidelity since 1934 | London

LEAK Stereo 20 Valve Tube Amp & Varislope | by Masaru Nishioka
LEAK Stereo 20 Valve Tube Amp & Varislope

In 1934 Harold Joseph Leak founded H.J. Leak & Co in London, UK – and promotes the company with his own name, adversting himself as “Sound Engineer – Technician”. In 1936 Leak & Co. release a P.A. Amplifier, with exhibits at Olympia Exhibition. 13 Watts output using push-pull PX25 power triodes. 40Hz to 12kHz +/- 1dB.

H.J. Leak does not appear in listings of exhibitors for Olympia, so the company may have used another company’s stand for the exhibit). This amplifer was supposedly advertised in Wireless World around 1938, although a search has failed to locate the advertisement. About 1949/1950 the Leak “550” two-way moving coil loudspeaker was released. This loudspeaker was used in the many live-versus reproduced sound demonstrations Harold Leak conducted. Harold Leak died on August 27, 1989.

Soundcraftsmen | California | USA

Soundcraftsmen was a manufacturer of high-end audio stereo components located in Santa Ana, California, United States. The company was founded in 1961 by Ralph Yeomans, a concessionaire in Fedco (a discount membership store chain in southern California, until the chain closed in 1999). Early Soundcraftsmen components included tube-type receivers and amplifiers.

Ralph Yeomans and Charles Gassett, a southern California audio equipment representative and international marketing entrepreneur selling Coastron Sherwood Electronic Laboratories receivers at the time, had an interest in expanding the brand nationwide. Ralph and Charles decided the first product was to be an equalizer, something not already on the market. They employed an electronics engineer, Paul Rolfes, in 1968 to design the equalizer. It was introduced by Charles at the 1969 CES in New York. National distribution started in late 1970. In the mid 1970s they introduced their line of preamplifiers and power amplifiers, including the first preamplifier/equalizer combo. Soundcraftsmen equalizers and their compact “brick” style power amplifiers gained a sizable following among audiophiles during the 1970s and 1980s. All Soundcraftsmen equalizers and amplifiers were made at the company’s Santa Ana, California facility.

BRAUN Design Collection | app. 1000 pcs for Sale

The BRAUN design collection consists of approx. 1000 different pieces, mainly from the years between 1955 and 1985. It is probably one of the most complete private BRAUN design collections of this period.

The collection shows how Dieter Rams und the BRAUN Design Department, starting from 1955, managed to give technology a clear shape (form follows function), wrapping it in modern materials. The domestic appliances in particular reveal the impact of “BRAUN Design” on other designers and their product engineering. The collection is either suited for a private collector or a design or technical museum. The innovative aspect becomes evident especially by comparing it with the technical products of other manufacturers of the same time period. Dieter Rams can be regarded as one of the best and most influential designers of the 20th century.

About the BRAUN Design Collection

Part of the Braun Collection
Part of the Braun Collection

The collection was created between 1979 and 1981 during my studies of architecture. In 1991 it was joined with a second collection in order to choose the best among 200 double items. Since 2010 the collection has been further extended. Most of the pieces are in a good or very good state even though the function of the devices has not been tested as most of them have been standing idle for more than 30 years.

Braun Collection Catalog shows only part of the collection as it was issued about 20 years ago. However, the list of items and the pictures of the storage facilities are up to date. The collection is completed by numerous brochures, manuals, posters, books, spare parts and so on. There are also some devices from the years before 1955, just to show that at that time they did not differ a lot from the products of other manufacturers.

Minimum asking price for the complete collection 350.000,– Euro

Grommes Precision Electronics | USA

Gommes Advertisement
Gommes Advertisement

William “Bill” Grommes founded Grommes~Precision Electronics, Inc. in March of 1946. For more than six years Grommes~Precision called the corner of Milwaukee and Erie in Chicago its own. Began as a company that designed and manufactured signal tracers, Grommes~Precision soon evolved into consumer audio. The name “Grommes” was adopted specifically for Grommes~Precision Electronics’ line of consumer hi-fi products.

Chicago Mayor Daley (l) presenting Bill Grommes (r) with a Pioneer in High Fidelity Award

Lead by chief engineer and audiophile, Al Hart, Grommes became a pioneer in high-fidelity. The Grommes line started with mono block tube amplifiers, but soon evolved into pre-amplifiers, integrated amplifiers, stereo amplifiers, and tuners. Demand for quality high-fidelity amplifiers grew substantially and in 1952, Grommes~Precision moved its operations to Franklin Park, Illinois, just outside of Chicago.

By 1955, Life Magazine declared Grommes one of the best buys in hi-fidelity. Not only for its 55PG amplifier, but also it’s LJ-3 “Little Jewel” tube amplifier kit. By far, one of Grommes’ most popular products was the “Little Genie” and “Little Jewel” build-it-yourself tube amplifier kits. The kits came with a full-color instruction guide and all the parts one needed to build their own 10 watt tube amplifier. It was “So simple…it’s like magic.” To this day, many an audio engineer claim they first got the “audio bug” from assembling their own Little Genie kit. Others sometimes got even more…

EICO | New York | USA

EICO was established in New York City in 1945 to manufacture electronic test equipment in kit form. A wide variety of test equipment remained the company’s mainstay during the time it was in the electronics business, however EICO often augmented their product lines with what was thought fashionable. For example, in the late 1940s it offered Geiger counters in response to public interest in uranium prospecting. In the 1950s and 1960s, they offered amateur radio and electronic test equipment. Their largest secondary market was audio equipment.

In the late 1960s, EICO introduced a line of solid state electronics audio equipment referred to as Cortina. EICO left the audio market in the late 1970s and the electronics market some time later. EICO existed as a property management company until 1999, when the company was liquidated at the request of the shareholders.

Here’s a magnificent 1921 Magnavox AC-2 amplifier. The amp is original, it’s working, it’s in excellent condition (still has its original Magnavox hang tag and cabinet label), and it comes a good pair of early, tipped amber glass UV-201 tubes. The tubes have been tested in the amplifier, and they still work. The AC-2 was designed to be used with either radio or PA input, with B+ plate voltages running as high as 90v. It can be used with almost any 1920’s battery radio or crystal set and can be powered by either dry cell batteries or a regulated DC power supply (such as an ARBEIII).

Detail
Detail

As you can see in the photos, the condition of this amplifier is excellent throughout. The panel is beautiful and undamaged, with legible engraved lettering and original nickel plating on the control assembly that still gleams. Cabinet is likewise in excellent condition, with an original finish that’s still as smooth as satin and an original full-color Magnavox decal that’s almost perfect. Chassis is clean and correct and original, and the huge original Magnavox AF transformer is still good. The 1st stage rheostat is open on a single turn at the very beginning of its travel, but this has no effect on the functionality of the amp, as the rheostat is in the off position when the stator is at that setting anyhow. Both rheostats gradually raise and lower the voltage, as they should, and both amplifier stages work properly, as you toggle each one off and then on. A few of the binding post nuts have worn threads, but they can still tighten down on battery wires.

The Magnavox license on the underside of the base is original and the original hang tag is in excellent condition. If you want to operate the amp, you’ll need a regulated DC power supply or high current, low voltage dry cells for the tube filaments (1 amp) and high voltage, low current batteries for the tube plates. Please note: this is not an AC amplifier. You do don’t simply plug it into a wall outlet. Also, it must be impedance matched to both input and output devices, and it was designed to be used with early 1920’s radio and public address devices, not 1950’s audio gear. Please know what you’re bidding on. Depending on what type of input device you’re using, and how that device is grounded, a separate, dedicated DC power supply may be required for the amp.

Western Electric Company | WECo | USA

Western Electric 92A Public Address Amplifier
WE 92A PA Amplifier

Western Electric Company (sometimes abbreviated WE and WECo) was an American electrical engineering company, the manufacturing arm of AT&T from 1881 to 1995. It also served as the purchasing agent for the member companies of the Bell System. In 1929, Western Electric was also a big player in early cinema sound systems. It created the Western Electric Universal Base, a device by which early silent cinema projectors could be adapted to screen sound films. It also designed a wide-audio-range horn loudspeaker for cinemas. This was estimated to be nearly 50% efficient, thus allowing a cinema to be filled with sound from a 3-watt amplifier. This was an important breakthrough in 1929 because high-powered audio valves were not generally available back then. Western Electrics’ reputation for sound management was such that in 1949 President Truman requested that Western Electric manage a major defense laboratory, Sandia National Labs.

Marantz Monoblock Tube Amp

The first Marantz audio product was designed and built by Saul B. Marantz in his home in Kew Gardens, New York. The company had a major influence in the development of high fidelity audio systems, and reached the high point of their success in the mid to late 1970s. During the 1980s, while owned by Philips, a pioneer in compact disc technology, Marantz built some very well received CD players, but other products in the line were not as successful as in the past.
