|MARK LEVINSON ML-6AL
Control amplifier which attained perfect monophonic
recording-ization based on ML-7L.
A cross interferencee is suppressed by
considering it as 4 case structures where all control amplifier on either side
was made to become independent of a power-source part (PLS-154L) on either side, and the improvement in a tone quality is aimed at.
The basic design has
inherited the design concept of ML-7L, and has adopted the block structure by
circuitry and the plug-in circuitry of only phone amplifier and line amplifier.
Furthermore, one line of a phone and a line each accept an input, and it is also
making a control into the simple structure of only a volume, and is planning
whether it is the further high purity.
The decoupling capacitor of a
power source is extended to the space which was vacant with simple-izing and
monophonic-recording-izing of the circuitry.
Wooden cases are attached.
There were L3 plug-in card of the high gain only for MC cartridge and an
L3A plug-in card in phone amplifier as an option.
