Vintage Marantz Superscope A-260 Stereo Amplifier MINT

Description :
So here it is. I have been talking about listing this for weeks and a lot of people wanted to see it already. Here is a 100% Brand New, Never Used, Factory Sealed (besides to take pictures) Vintage Marantz (Superscope) A-260 Stereo Amplifier. I have done a lot of research on this item and I am yet to come across another in this condition. This is a amazing vintage amp from the 1970's and for all I know it could be the last brand new of its type. It is still in the box it came in from the manufacturer and wrapped with factory seal. That means there are no scratches, dents, dings or anything of that sort. This has been stored in a finished, temperature controlled basement for around 40 years and never moved an inch in all that time. This is without a doubt a collectors dream as well as an amazing amp that is built to last. They do not make them like this anymore to say the least. In the box is the amp, the owners manual and the schematics of the amp. Here is some information from the owners manual and product specs will be left below. FOREWORD Marantz Superscope Model A-260 is a high-quality solid-state stereo amplifier incorporating 27 silicon transistors and 10 diodes. It has been designed with a large number of features and performance capabilities to give you years of outstanding stereo enjoyment. In addition, 4-channel capabilities are provided by Superscope's unique QUADRAPHASE control. Operation of the unit is not complicated but it's flexibility can only be fully appreciated when a little time is spent becoming familiar with its controls and connections. For quick identification of these controls and connections, references to them have been printed in bold face type exactly as they appear on the front and rear panels of the amplifier in the owners manual. Here is some info from the users manual. If you have questions regarding anything please ask. Rear Panel Connections All signal connections and jacks on the rear panel of the A-260 are for permanent connections, and are arranged in stereo pairs. To avoid confusion and cross connection channels, connect one cable at a time between and A-260 and other components of your music system. Connecting Your Loudspeaker Systems A lot of information is covered in the Manual and if you have any questions do not hesitate to ask. Rear Panel Information Quadraphase loudspeaker terminals are provided on the rear panel of the unit to provide simulated 4-channel or enhanced stereo performance. Rear Panel Also Includes: Tape Out Jacks Tape In Jacks Din Connector Tape Jacks Tuner Jacks Phono Jacks Aux Jacks Inter Coupled on-off Main In Pre Out AC Outlet, Unswitched AC Outlet Switched AC Line Cord Front Panel Information: Power Switch Loudness Switch Selector Knob (to chose Tape, Tuner, Phono, Mic or Aux) Volume Control Balance Control Bass Control Treble Control Speaker Switches (for Main, Remote and Quadraphase) Mono Switch Tape Mon Switch Phones Jack Mic/Aux Jacks More uses for the A-260 include: A multi-channel speaker system can be formed by turned off the INTERCOUPLED ON-OFF switch and connecting the PRE-OUT jacks to a cross over network that seperate the audio spectrum in three ranges: Highs, mediums and lows. The outputs of the cross over network are conducted to the respective sections of the speaker system through suitable stereo power amplifiers. Marantz Superscope Model a-260 can be used as one of them; other two should be added to complete the installation. When The INTER COUPLED switch is in the OFF position, the preamplifier section of the A-260 is disconnected from the power amplifier allowing the insertion of audio devices such as equalizers, 4-channel decoders, etc. TECHNICAL SPECIFICATIONS ± Main Amplifier Section Instantaneous Peak Music Power.......................66 w/8? 80 w/4?

If you wish for other shipping methods please ask. I know this is going to make somebody very happy and I wish I had more than just one to offer. Get it before it is gone and thank you for stopping by to take a look. I just wanted to point that there is some history to this item. My grandfather owned 3 major AM radio stations (WREL Being the largest) and was also part of Kiss FM ownership back in the 70's and if you look at the second picture in the listing you will notice it says Promotional Merchandise on the box. This was an item sent directly to WREL from Marantz as a Promotional unit and he brought it home and never used it. Just an interesting bit of history I thought I might add. Thanks everyone that has stopped by and taken a look.
