Control amplifier which added the enhancement based on ML-6bus logic circuit, and was developed.

Simple & straight-ization is thoroughly attained by a basic circuit's being what monophonic-recording-ized ML-7AL, making a cross modulation on either side there be nothing by having a monophonic stream composition, and deleting functional sides, such as a tapes monitor and a balance control.
Moreover, the cross interferencee is suppressed, while the main-unit part (ML-6bus logic circuit) and the power-source part (PLS-154L) serve as a design which dissociated and became independent and realize low-impedance-ization by three buslines of a plus-or-minus grounding.

The highest-class Teflon capacitor which has adopted as an internal part what was selected carefully and can be obtained in a RIAA circuitry those days,The P&G requests-for-price-quotations volume by the conductive plastic conductor and platinum plating bar line which entered the serial number and the date in every piece, and were checked severely etc. is adopted.
Moreover, lead wire was required minimized and the virgin silver lead wire of a Teflon insulation is adopted.

L3 plug-in card of high gain and L3A plug-in card which can link MC cartridge directly are prepared for phone amplifier as an option.
