USA based hi-fi and audio company run by Bert Berlant, originally the trade name was Berlant, later Berlant-Concertone and finally just Concertone,
primarily known for their open reel recorders. The early designs were by Berlant himself and manufactured in the USA. However later recorders from this company were rebadged TEAC products. The company fizzled out in late 60's early 70's. Not to be confused with the French amplifier manufacturer named Concertone active in a similar/slightly later time frame.
Despite the many horrors of World War II it brought forth many technological breakthroughs and pressed our countries greatest minds to contribute in their respective fields. Bert Berlant was a Signal Corps engineer with an open mind and the ability to implement non-conventional approaches to engineering problems. He developed a 70 mm combat camera for battlefield reconnaissance photography, a Robotron camera for the U.S. Medical Corps, and was a key contributor to many other important war time developments.
When the war ended, like so many other US engineers, Berlant was uniquely educated to contribute to 
consumer/professional technology industries. He started Berlant Associates Inc. in 1946 andbegan producing hi-fidelity and professional grade audio equipment. His components were of the highest quality and extremely innovative. Berlant particularly excelled in the field of magnetic tape recorders; today he is viewed as a leading pioneer of this format, helping to mature it into the professional standard.
Two different product lines were produced by Berlant, the Concertone series for high-fidelity home music systems and the Berlant professional series, components forrecording studios and radio stations. These tape decks are of outstanding design and build quality, rivaling the finest decks of the era from Ampex. Emmanuel Berlant left Berlant and Associates in 1956 to become president of Stephens Trusonic, Inc.

Emmanuel (Bert) Berlant died 1985 April 22, at Cedars-Sinai Hospital, Los Angeles, CA, after a long illness. A fellow of the AES and a member of the HollywoodSapphire group, Bert enjoyed a long and successful career as an electronic engineer, consultant and manufacturer. He became associated with the New York experimental theater group during the mid 1930s and was involved primarily with set design and lighting. His efforts to improve sound and lighting led to intensive study in electronics and research in the field of optics.
During the early war years (1941 - 1943) Bert became the director of research for Optical Research, Inc. of Long Island, New York. One no- table product developed under his direct supervision was a70 mm combat camera for Signal Corps battlefield reconnaissance photography. In 1943 Mr. Berlant went to the U.S. Signal Corps Photo Center in Astoria, New York, where he was retained as an expert consultant to the Signal Corps Pictorial Engineering Research Laboratories. He remained there as supervisor of the laboratories until the end of the war in 1945. During that time he designed and patented the Robotron camera, subsequently designated the approved, general purpose camera of the U. S. Medical Corps. After moving to Los Angeles in 1946 he and several former associates of the Signal Corps Center founded Berlant Associates, Inc., which designed, manufactured, and distributed high-fidelity home music systems.
From 1949-1953 the company introduced several new multitrack stereophonic , magnetic tape recorders. Two different series were presented-the Berlant Concertone series for high-fidelity home music systems and the Berlant professional recorders for recording studios and radio stations. Bert won a reputation as a pioneer in the manufacture of stereophonic and high-fidelity music equipment.
During this period the industry was changing from radio vacuum tubes to solid state (transistor) operation. Bert's companies were one of the first manufacturers to convert to total solid state equipment. It was during that time that Bert became a fellow of the Audio Engineering Society for his contribution to the art of magnetic recording. Active in trade associations, Berlant helped found the Institute of High Fidelity Manufacturers and served for four years as the West Coast Electronic Manufacturing Association representative on the board of directors of' the National Trade Show. 
In 1956 Bert left Berlant Associates and became president of Stephens Trusonic, Inc., a manufacturer of professional microphones and theater loudspeaker systems. He redesigned the entire loudspeaker line and introduced it to the high-fidelity home music market. In 1960 he became an independent engineering and product management consultant for various electronic firms. In 1963 Packard Bell Electronics, Inc. enticed Bert to join them with an unusual working arrangement. During the next few years he served in the following capacities: product manager, senior research scientist, corporate planning, assistant to the president, and as director of operations for Teledyne Commercial Products. Inc.
An ardent student and collector of southwest American lndian art, Bert was president of Amerind Art' Inc" in quality American since 1972. In the Indian art last few years he designed a radically new loudspeaker with improved acoustical ambiance. This loudspeaker designed for digital use was appropriately named the "Omnient" for its design shortly before his death. Berlant will always be remembered by his close friends and associates as a dedicated, innovative engineer with an open mind, trying nonconventional approaches to engineering problems. He is survived by his wife Gertrude and two sons, Tony and Jeffrey.

Phantom Productions received this information from Jerry Norton who worked with American Astro-Systems as they transitioned from Concertone tape recorders to supplying high tech gear to the military.
"You asked about my thoughts on the Berlant/Concertone evolution. Here is the story according to my recollection and personal involvement.
In 1962 Berlant sold the Concertone line and rights to the name to “American Astro-Systems” a small Aerospace firm in South El Monte, CA.
It was in this time frame, 1963 that I recall American Concertone licensed the rights to manufacture the Model 505 to TEAC (Tokyo Electro Acoustic Company) who as we know continued to manufacture this baseline through 1970. 
TEAC (see motor label left in the Concertone 93 built in 1962) produced the 505 and some of the early Concertone recorder subassembly components in Japan as well as DOKORDER.
However, the final assembly and checkout took place in the US (Culver City and South El Monte, CA).
Berlant left the company in 1963.
After the acquisition, the Concertone management team (Arne L. Berg / Kenneth M. Williamson) and and technical personnel (Deiter Brandt and Richard Schullenberg) were relocated from Culver City, CA to South El Monte, CA where Arne and Kenneth continued to pursue the development of an automatic tape reversing mechanis
m to permit bi-directional playback on an existing four track tape recorder having an asymmetrical capstan drive system .
This tape drive technology evolved into the American Concertone 800 Series “Reverse-O-Matic” High-Fidelity consumer product line and it’s little brother the AC or battery powered Model 727.
The parent company (American Astro-Systems) ultimately changed its focus in 1964 to militarized avionics and high environmental multi-channel recording products and became “Astro-Science Corporation.” Astro-Science (then owned by Tracor Inc.) was later sold to “Bell & Howell” in the 70’s and became part of the DATATAPE division.
The recording systems produced became very specialized and primarily used in Airborne, Space and Shipboard applications.
I was a key part of the engineering / marketing team starting at American Astro-Systems that evolved the Hi-Fi magnetic tape recording technology into the Military and Government program markets with the help of some early Co-axial reel tape drive mechanism developments (see attachment).
In fact, the early airborne reconnaissance intelligence recording systems for the U2 and SR-71 aircraft during the “Cold War” were built by the Concertone/Astro-Science Corporation Engineering team.
The Concertone product line ceased production around late 1966 (Arne Berg and Kenneth Williamson departed) and the name was sold to Monarch Electronics International Inc. of North Hollywood, CA (and Japan) in 1968– where it resides today.
Strangely, the 4 and 8 track tape players produced in 1969 by Monarch were marketed under the “Cal-Best Electronics” moniker.
The Concertone name plate was never used on another audio tape recording product again and 1987 saw the end of consumer recorder production as we all knew it.
I have traced a history time line of the Berlant legacy going back to 1951 when the Model 1401 was marketed under the “Berlant Associates” name.
Hope this information is of help to you.
Regards,
Jerry
Teac Berlant Concertone connection
More: In the February, 1982 issue of Modern Recording and Music magazine, James Rayton with the Ascot Recording Studio in Hollywood, CA wrote:
"probably around the early '60s, the (Berlant/Concertone) assembly was moved to Japan, and around the same time, I believe, the company became known, paradoxically, as "American Concertone"; their product emphasis gradually moved into the mid-to-high-end consumer category, (and occasionally appeared under other trade names like 'Concord'). Whatever remains of the company today is perhaps better known as TEAC, who interestingly, continued making the old Concertone 90 at least through the late '60s, with only a change of nameplate (and probably solid-state electronics) and a different model number."
Also from on line comments (not verified) "Some history, Bert Berlant and his cronies founded Berlant/Concertone. Later on, Bert Berlant retired and the other partner continued the company. He elected to use Concertone electronics on the early machines but use Teac transports. Later on to the end of the company, American Concertone engineered various recorders. Berlant/Concertone decks to the early American Concertone decks with Teac transports, Semi Pro! Last American Concertones, Consumer decks".(tapeheads.net)
On line forum comments (not verified) "Most of the Berlant Concertone machines were mono. Berlant Concertone tape recorders were really semi-pro decks. Beloved of dilettantes in the day. The original ones were entirely made by Berlant in the USA. The middle period used Berlant electronics (USA made) and Teac transports made in Japan. The last of the Concertones were made in Japan by various vendors. Teac didn't officially import their decks here until 1967 (also ReVox's first year sold in the USA). All of these machines are difficult to obtain spare parts for. The early and middle period decks are usually decent performers.
Those were made by TEAC about the time Berlant sold out to TEAC and was renamed American Concertone (ironic name change). It was also sold as the TEAC 507/508. 507 is the stereo version and 508 the mono version. I have one each of the TEAC and Concertone versions". unknown source
