Marantz Model 33

Commentary

A preamplifier with built-in control functions such as slide-type tone control.

The tone control section uses a slide-type volume in which the left and right channels are independent. By making the position visible at a glance, the adjustment condition can be easily understood.

With a tone control release switch, flat characteristics can be obtained with one touch operation.
In the Loudness position, the sound is corrected so that when the volume is reduced, it does not sound as low as bass.

Built-in headphone amplifier for low-impedance headphones.
This headphone amplifier has an independent volume control.

Slide type volume and balance volume are adopted.

The front panel is equipped with a jack for tape-recorder dubbing so that you can easily add decks.

Center channel output terminal is mounted.
This jack has its own level control.

Equipped with high filter and low filter.
Each attenuation point can be switched in two steps.

IC is used for the low-level amplifier stage, and high reliability and performance are obtained.

The wood case was sold separately as an option.
