Have some additional information about the Model 2275 Receiver? If so, I would sure appreciate it
if you would add it here: Add Data Form
The database currently contains "slots" for many AM Tuner, FM Tuner, Amplifier and Preamplifier specifications,
as well as many of the controls and features Marantz has made available on these units. You can check the Sample Unit to see all of the database slots. You
might even be surprised at some of the slots that are available. However, if you come up with something that's not in the Marantz Classics database, either a specification
or a feature, I can add it in just a few minutes, along with specific details about that feature for any model(s) you know of. Don't be shy - tell me!
These listings can only be as good as the information in them. With your help, they will improve over time. Please accept
my heartfelt thanks in advance for anything you can contribute.
