EDCOR is an acronym for Electronic Development Corporation. EDCOR was originally a public Utah corporation in the early 1960’s that originally developed wireless microphones and had the first US patent. The original microphones operated on the FM broadcast band and were tunable, so one could select an open frequency in the area of usage. The market was outstanding in the high entertainment areas, like Las Vegas. EDCOR had many celebrity singers using our wireless equipment and some not so famous like Oscar, a sea lion at Sea World.
The company was sold to a private Nebraska corporation, Product Assruance Corporation (PCA), in 1971 and continued under the name of EDCOR . The main products continued to be the wireless microphone, with the frequencies being shifted to the 30 to 50 MHz bands.
By 1974 EDCOR had moved to southern California and located in Costa Mesa. At that time, a medium sized company, Video General Corporation was acquired. The sales outpaced the ability to finance the growth. EDCOR had to contain growth and new product development. The video and Teletype machine sales and installation market was booming but the profits were minimal.
In 1976 the decision was made to enter the commercial sound market and to leave the video and Teletype market behind, which turned out to be good move as the onset of FAX machines was nearby. The product development for the commercial sound market was going strong and the wireless microphone market was expanding.
EDCOR moved to a larger facility in Irvine, California, about 3 miles from Costa Mesa. In about 1978 the commercial sound amplifier sales were outpacing wireless microphones and the addition of an economical automatic mixer continued to open the gap. But the gap closed after EDCOR announced wireless translation and hard of hearing systems and the new 150-210 MHz microphone systems. Difficulties arose as several large organizations wanted to acquire EDCOR at that time and several substantial legal problems were encountered. However, after several years and many dollars EDCOR survived, weakened but not out of the game. Shareholders lost interest and the company meandered for several years.
During these interesting periods, EDCOR did develop the first digital amplifier and the multiplex snake system. EDCOR also was the first to develop the wireless electrical guitar system for musicians. Unfortunately the digital amplifier, multiplex snake and wireless guitar system were 10 years ahead of the time, and sales were difficult to achieve.
In 1982 several engineers from the old Peerless Transformer Company started a company called Delta Magnetics and tackled the power audio transformer market. EDCOR was a likely ally since we used power audio transformers on many commercial sound amplifiers. EDCOR acquired the Delta Magnetics product line and manufacturing facilities within a few years and expanded.
In 1984 EDCOR was moved to Santa Ana, California, about 2 miles from Irvine to an another facility. Commercial sound products continued to be developed. EDCOR came out with the first True Blue Audio Transformer. The wireless microphone market was impacted with competition from foreign import. The wireless market for EDCOR began to decline. The transformer and commercial sound sales offset the wireless decline and in 1989 the decision was made to sell the wireless microphone division and assets. It was sad to see the wireless division go but this left EDCOR even stronger with the commercial sound and power and audio transformers.
In 1989 EDCOR received a letter from the Carlsbad, NM Department of Development. The Mayor of Carlsbad requested a meeting with management to discuss the possibility of EDCOR moving to Carlsbad, NM. EDCOR was chosen from a list of high tech California companies (along with several others). After several months of discussion with Carlsbad officials, EDCOR committed to the move in late 1990. Several of the management team invested in EDCOR at that time, purchasing the outstanding stock. They also financed the move, purchased land and a facility and provided working capital and a new commitment.
The California facility was closed in late November of 1990 and the ****New Mexico facility**** was open for business the first week of January 1991. EDCOR Electronics was then reincorporated in New Mexico.
Since mid 1980s, EDCOR's transformer sales has been growing dramatically. It has been a major part of EDCOR. EDCOR's transformers has been used all over the world and beyond. In 1997 EDCOR launched its web site and sent the True Blue Audio Transformer around the world and into space. The response was overwhelming. EDCOR started picking up new customers in other sound markets and industries. After about a year EDCOR dropped the power transformer line and concentrated on the audio transformer market.
By the new millennium EDCOR had pick up a large number of other electronic manufacturing customers to produce custom transformer for their products. In 2001 EDCOR Electronics made a hard decision and dropped their large power and mixer amplifiers and to begin to phase out of the industrial mixers. The decision was very hard and took a few years to come to to. The audio transformers and smaller audio products, that we call gadgets, has overshadowed the sales of the amplifiers and mixers. The people that had been with EDCOR since the 70's felt sad, but it also inspired them to push and develop new gadgets and audio transformer manufacturing techniques. By the drop of the amplifier and mixer line in turned open the door for old competitors to purchase EDCOR's audio transformers for their products. This again was a wise move and in a few years EDCOR's sales of audio transformers was bigger then ever.
Ever since EDCOR has moved to New Mexico their sales have been growing. In 2005 EDCOR was approached by a number of customers to produce a high quality line of transformers for the tube and classic audio industry. It seem that hobbyist, professionals and other manufactures are looking for good quality and inexpensive transformers for this industry. So, EDCOR dug deep and pulled out some of their old time records and with the new techniques that EDCOR has developed over the year EDCOR started to develop a new line of classic transformers.
In 2006 EDCOR lunched the Class X series of classic audio transformers and had a large following at once, do to the greatest add campaign; "word of mouth". EDCOR wishes to thank all that have support use in this adventure and for passing on the good word.
EDCOR's sales had been mainly contractors and distributors. Since the launch of its web site, EDCOR's customer base has broaden and grown to manufacturers, educational institutes, R&D groups, government agencies, medical, scientific, hobbyist and communication industries. Some of our customers have said that they would not buy anything other than a True Blue. We at EDCOR are proud of our past and look to the future with new ideas and products in the development and are going to keep you wanting our products and service.
In 2011 EDCOR felt it was time to open their online store. EDCOR waited this long because of the problems they ran into with the calculating of shipping costs. With the new applications on the market and better features, EDCOR developed their website to take orders.
EDCOR is going strong, constantly developing new products and is focused on the future.
