Add a Tape Recorder to Your Phono (Feb, 1960)

I’d like to see the reverse. You could put two records on a tape deck and play in stereo!

Add a Tape Recorder to Your Phono

• With the Gramdeck you can turn your phono into a tape recorder—or back into a phono— within a few seconds. The Gramdeck just slips onto the turntable as easily as a record; the turntable drives the tape spools and the phono loudspeakers provide sound reproduction. A pre-amp/control unit which uses transistors and printed circuits and which is installed permanently on the phono in a few seconds, is part of the kit.



A rare find in a dusty attic led to Louis Kernstein’s role as an expert on old music machines.

TWENTY-FIVE years ago, Louis Kernstein found an old, dusty victrola in the attic of his family home in Freehold, N. J. The machine was in sad need of repair and Louis scoured his neighborhood for parts. He didn’t find the parts but he did discover all kinds of music boxes and machines which formed the basis of his present remarkable collection.

Machine Tears Apart And Rebuilds Speech (Sep, 1939)

Machine Tears Apart And Rebuilds Speech
A MACHINE that tears speech to pieces and remakes it in new patterns has been developed. Use of these machines for sending and receiving telephone messages would make wire-tapping impossible, unless the wiretapper had a machine with which to listen. Anyone listening with an ordinary receiver to a call made through the machine would hear only unintelligible sounds. Other possible uses for the machine are the making of voices for animated cartoons and in improving newsreel vocal accompaniment where excitement might make parts difficult to understand.

Uses Record in Rehearsing Part (Apr, 1934)

Uses Record in Rehearsing Part

PAUL MUNI, movie star, learns just how his voice will sound in “talkies” while he is memorizing his lines.

He reads his lines into a dictaphone and then plays the record over and over, hearing his own voice and thus correcting errors that creep into his speech.

Lenses Promise No-Hands Phone (Oct, 1949)

Lenses Promise No-Hands Phone

BEING a good engineer, Dr. Winston E. Kock is a lazy man. He thinks it’s too much trouble to lift up a handset every time you want to talk over the telephone. His idea of a telephone is a little black box you never touch—just talk and listen to.

Since Dr. Kock is a physicist-engineer for Bell Telephone Laboratories, he did something about his idea. He developed lenses that focus sound, a necessary preliminary to the lazy-man’s telephone. The telephone itself is still only an idea, but the lenses have been made and should have many uses.

You can understand why lenses are necessary if you’ve ever held an old-fashioned telephone receiver near the transmitter. The transmitter picks up the receiver’s sound, which keeps going around the circuit until it is a howl. A lens would direct the receiver’s sound at the user and keep it away from the transmitter. (“Intercom” systems do have combination receiver-transmitters, but you must press a switch to talk—more work than holding a handset.

Fish “Talks” on Radio (Oct, 1940)

Fish “Talks” on Radio
A talking catfish startled listeners to a recent broadcast from a New York City radio station. When removed from his tank in the Staten Island, N. Y., zoo, the conversational catfish, a native of the Amazon region of South America, made curious sounds into the studio microphone as part of a natural-history program.

SOUND MOVIES give the Los Angeles police an additional means of recording automobile accidents. Communications equipment from B-29s is now in use in patrol cars.

Vanishing Microphone lets the starts shine (Jan, 1951)

I’m really not sure how this microphone is supposed to vanish. Is it just small? Or made of lucite? Or does it come with skins so you can match an outfit? Or is it really some sort of super sophisticated active camoflauge system the military developed to hide…. um…. microphones?

Vanishing Microphone lets the starts shine

Now you see it, now you don’t!
RCA’s new “vanishing microphone” is plainly visible when standing alone—but let a television performer stand before it and it seems to disappear.

Eavesdropping Mike Listens In on Umpire’s Scraps at Ball Park (Dec, 1940)

Eavesdropping Mike Listens In on Umpire’s Scraps at Ball Park
So THAT baseball fans may eavesdrop on arguments between the umpire and players next spring, a “disappearing microphone” has been included in a new public-address system at a Wichita, Kans., stadium. Pressing a foot lever allows the microphone to pop from its underground box near the home plate. Through loudspeakers, the spectators then enjoy the novelty of hearing what is going on. In case a dispute becomes too heated for sensitive ears, the mike hastily retreats. As at left, it may also be used for announcements.
