Got a 1072/1050 owners manual in response to Ashley Sep 1 2005 post. Don't think this post will still be of interest now, but who knows. Also have a 1050 amp to match. I've heard so much about this amp I don't know what to think. Bought about 30 years ago....blah blah. Told it's X-rare. Don't use it, but don't want a classic going to waste,(it's under the house in a plastic bag at the moment). Don't know where I'm going with this. F1
BTW, the 1050 isn't really a classic. It was built during Marantz's Superscope days and represents a not so great time period for Marantz as a company. There are, however, people who like the old Marantz gear or believe they are buying something from another period in Marantz's existence and will pay some money to own a working model.
Unless you live in the desert an amplifier stored in a plastic bag in a non-controlled climate will be hard pressed to be in good condition after just a year's time.
Do not pull the amp out of the bag and immediatey plug it in to check operation. The amplifer needs to be brought up to full power very slowly while being monitored with a scope. Doing otherwise might get the amp working temporarilly but the chances of it failing within a week after the new owner plugs it in are very high.
If you are serious about selling this unit, take it to a shop and ask them to bring it up to full power on a bench while monitoring its current draw. It needs to run with a load at 1/3 power for at least an hour to get a passing grade.
If they say it passes without problems, at least you've done the proper test and can pass this information on to a prospective buyer.
The Model 1050 was made in 1979/1980 but is a pure Marantz ,because Marantz only sold his company to Superscope but Superscope was using original Marantz parts like in the good old days before and was responsible for the Marantz sale in the U.S. !They also had there own Superscope by Marantz Recivers built with original Marantz parts in Asien countries,but the quallity was not really so bad because everything was still designed in Chatsworth California !
