Threc-Spccd Record Phn cr Announced bx RCA \^icr()r jL\. nlw .mil unproved type of "Victrola" three-speed record player, which makes it possible, with a single turntable to provide qualirj' reproduction from records of all three established revolving speeds, has been placed on the market by the RCA Victor Division. Under development for more than a year, the new instrument, available in four mixiels, marks the introduction of RCA's tirst three-speed record-playing system. Heart of the new instrument is a novel slip-on 45-rpm spindle which houses the automatic record-changing mechanism of the 45-rpm system. The larger slip-on spindle fits over the permanent spindle and converts the new record player into an authentic 45-rpm instrument, with all the engineering advantages and performance features of the "45" system. With the slip-on spindle removed, the instrument, at the twist of a selector knob, will play either 78-rpm or 33'3-rpm discs. Completely automatic, the new record player: Plays up to 14 45-rpm records at one loading; plays up to ten 12-inch or twelve 10-inch standard or long-playing discs at one loading; plays up to ten intermixed sizes of 78-rpm, or the same number of 33'3-rpm records of intermixed sizes; stops automatically after playing last record of any of the three speeds; provides two separate pick-up points in a single tone arm, one for playing 78-rpm discs and another for the 'l5-rpm and 33' vrpm records, and eliminates the need for record inserts. The new all-speed "Victrola" instruments include a record-player attachment which can be connected to any radio, phonograph, or television set. Other models are a self-contained phonograph with a built-in speaker and amplifying system; a self-contained ponable unit housed in a luggage-type carrying case, and a three-speed table model "Victrola" radio-phonograph. "Engineering advances now make it possible to inte- grate '45' facilities in an all-speed changer that provides reproduction of equally high quality from all types of records and, at the same time, retains all the advantages found only in 45-rpm instruments," said H. G. Baker, vice president in charge of the company's Home Instru- ment Division. Reriecting the simplicit>' of 45-rpm engineering, the new all-speed Victrola instrument features a single, lightweight tone arm for records of all speeds; a twin- p<iint stylus which is quickly rotated for playing either ~8-rpm or 45- and 33l<-rpm records by turning a tiny Three-speed record ployer installed in combination table-model radio-phonograph. lever mounted on the tone arm; a "guard position" protects the stylus when not in use; a single speed- selection control knob, and a single knob fi)r on-off- reject control. For 45-rpm. the operator need only turn the speed- selector knob to the proper speed. For either 78-rpm or 33y3-rpm, the only additional step required is to lift the large spindle off the permanent spindle, and adjust speed-selector knob and stylus. Every RCA Victor 3- speed record player has a specially designed receptacle to conceal the 45-rpm spindle when not in use.
