Marantz 18 Receiver

Marantz 18 Receiver

(1968-1972)
RMS Power Per Channel 40 @ 8 or 4 ohms, 20 @ 16 ohms
Damping Factor @ Load Impedance 30 @ 8 ohms
Total Harmonic Distortion (THD) 0.2% @ full power

With the exception of the cathode ray tube, the model eighteen is an all transistor receiver, based on the same advanced circuits used in the Marantz model 10B tuner, 7T solid state pre-amplifier and 15 solid state power amplifier.  It's circuitry includes 72 transistors and 76 diodes, a total of 149 solid state devices.

A tuner, pre-amplifier and power amplifier make up the three basic components mounted on a single chassis and sharing a common power supply.  Internal connections between these components have been designed to provide optimum performance from each component while retaining full flexibility.

The model eighteen allows the connection of two pairs of loudspeakers, headphones, a turntable and record changer, an additional tuner, a TV sound source, and two tape recorders for record, playback and tape copying functions.

It's flexibility will allow other connections to be made for special applications and it's performance is the equal of the finest separate component system of comparable power.

Dimensions: 18 x 6 x 16"
