    Abstract: The invention is directed to a semi-automatic record player. The record feed is instituted when the tone arm is moved manually to position its stylus element on the edge of the record which is to be reproduced. One form of the invention provides for the drop of a lowermost record of a stack by actuating the tone arm. A second form of the invention initiates the record drop following a manual movement of the guiding and supporting spindle in a direction axially of the spindle toward the record supporting turntable prior to a positioning of the tone arm. Each form of the invention provides for holding a stack of records prior to reproduction in a position substantially parallel to the record turntable. Further, the components are so arranged that all may be carried within a completely portable carrying case in which they are adapted to be enclosed. The complete unit is selfcontained and includes within the casing suitable sound reproducing apparatus, as well as all necessary amplifier components for energizing the sound reproducer in accordance with the record immediately being traced by the tone arm stylus.

    Abstract translation: 本发明涉及一种半自动唱机。 当手臂手动移动以将其触笔元件定位在要再现的记录的边缘时，记录馈送被设置。 本发明的一种形式通过致动色调臂来提供堆叠的最低记录的下降。 本发明的第二种形式在引导和支撑主轴在主轴的轴向方向上移动到记录支承转盘之前启动记录落下，在定位音臂之前。 本发明的每种形式提供了在与记录转台基本平行的位置之前，在再现之前保持一叠记录。 此外，这些部件被布置成使得所有部件可以被携带在完全便携式的携带箱中，其中它们适于被封闭。 完整的单元是独立的，并且包括在套管内的合适的声音再现装置，以及所有必要的放大器组件，用于根据立即由音调手指笔追踪的记录来激励声音再现器。

    Abstract: A cassette recorder amplifier system with a two stage preamplifier having direct current forward feed from the first to the second stage and direct current feedback from the second to the first stage to cause the second stage to operate without overloading as an input stage. The power amplifier has high direct current feedback and lower alternating current feedback for better linearity and more gain. Switch circuits and extra input terminals provide for recording on recording, aural monitoring of recording, and higher speed on fast forward and reverse.

    Abstract: A recording attachment partly self-supporting and partly supported and oriented by the turntable of a regular playback phonograph to permit recording on pre-grooved disks. The attachment includes a recording transducer sound-isolated by rubber grommets or the like and mounted on the same structure with a microphone and an amplifier.
