TYPE 70-D RCA HIGH-FIDELITY TRANSCRIPTION TURNTABLE
\
• This moderately priced transcription turntable has no superior — either in mechanical simplicity or in high-fidelity reproduction.
One heavy-duty synchronous motor provides the drive required for playback and recording. Mechanical filters and spring-clutch assembly completely isolate the platter and the fly-wheel from the motor — and assure even runningand smooth starts and stops. A high-quality
universal lightweight pick-up, with a diamond-point stylus, provides true reproduction— for either vertical or lateral recordings.
A hinged door on the metal cabinet makes everything easy to get at. There is ample space inside to house booster amplifiers and record-cueing amplifiers. There is also accommodation on top for an RCA 72-D (or 72-DX) Recording Attachment. And you will be able to
handle the new records designed to play at 45 rpm — by means of a simple modification kit soon to be made available. • • •
