It seems that we forget that Tentec is a "spin off" company of
Electro-Voice, a very highly respected audio company.
Spin-off is not quite right, but highly respected certainly is. Al Kahn
and his partner Lou Burroughs, who had started a small radio repair
business in South Bend, IN in 1927, and incorporated as EV in 1930.
Together, they built and operated one of the half dozen premier audio
companies in the US. In 1968, they. sold it to a conglomerate, Gulton
Industries. Both men were highly respected in the audio world, Lou the
engineer, Al the businessman. Lou wrote an excellent book on microphones
that was considered a prime reference for years. Among Lou's
accomplishments were the first noise cancelling mic, developed for the
military during WWII, and the first lavalier mic.And even their earliest
mics (the early 30s) included hum-bucking coils! Lou retired to Lake
Havasu City, AZ, and died in 1986. Al used his money to build Ten Tec.
There's an excellent profile of Al, written by David Reed for Sound and
Communications while he was still alive.
