9/17 Marantz 2270 engraved faceplate survey update.
1. It appears the long held belief that the engraved faceplates (champagne and silver) were made between serial numbers 1,000-5,000 for a total of 4,000 units is true.
2. Silver engraved units are indeed a rare bird as I have only 6 confirmed units out of a total of 66 from my survey. Champagne engraved units in my survey now numbers at 60 out of 66. Therefore, silver engraved units account for only 9.09% (6/66) of known units.
3. I still have gaps in my numbers as expected since I have only a 1.65% sample size. Most of the larger remaining gaps are between 3328-3566, 4201-4516, 4600 and 4900-5000. Because of the gaps the silver engraved units total could be as high as 25%. However, I still believe it will end up around 10% +|-.
So again if you have a champagne or silver engraved 2270 please forward the serial # to me and indicate if champagne or silver engraved. There is a photo in the beginning of this thread that shows the difference between the two. Of course an engraved unit has the entire front face plate engraved compared to the normal smooth lettering of the later models if your not sure what you have. Thank you again for any help.[/QUO
