Marantz Model Eighteen - The First Marantz Receiver!

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

The very first Marantz receiver! 

Sounds wonderful with both vintage and modern speakers. 

While all audio functions fundamentally work with this vintage beauty, unfortunately the oscilloscope no longer functions. 

We reviewed potential repair options during our troubleshooting, but a full replacement assembly would required that appears to be unobtainium today.

This Model Eighteen has other minor cosmetic and electronic issues as noted below, and would make a great restoration candidate or collector piece. 

We also currently have the matching and rare wood cabinet for this special receiver available here.

Important Notes:
• Scope non-functional.
• Aging carbon volume control causes slight volume discrepancy between channels depending on position of control.
• Faceplate has faded lettering and some scratches and blemishes from age.
• Some original cover screws missing.
• Power cord plug was replaced at some point in the past.

More from vintage Marantz documentation:

"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."
