This stereo has been serviced a few years ago. I have had the wood case stained and polished out about the same time as the service work. the switches and the pots have all been cleaned and work correctly with no issues. the tuner was aligned and the complete unit was disassembled during the cleaning. The stereo sound as good as it looks and every this work just the way it did when it was new. look at the snap shots and see for your self
This was my office setup for the last few years but now I am clearing out all my vintage Marantz equipment as my time is now taken up with other projects in my shop and I need the space.
