Corrections:
AU-907MR,606030271,mjs1 my mistake, I previously listed it as 606030272 and its in the database with an error in the last digit
I also respectfully submit that the dates listed in the Sansui Database for the B-2105 MOS (Vintage) and C-2105 Vintage are wrong. According to AudioHertage.jp/Sansui (which is not infallible) these were released in 1999 but sansui.us (Best os Sansui) lists 1997 for the release date. There are two B-2105 MOS (Vintage) listings in the database. Production date is listed as June, 2007. I believe these were actually produced in June of 1997. Mine, apparently, is from September of 1996. There is a similar problem with the C-2105 Vintage. AH.jp lists as release date of 1999, sansui.us lists 1996. There is only one listed in the Sansui Database with production date listed as December 2006 which, I believe, should be corrected to December 1996. Mine is from February of 1997. I believe that the old Sansui company was out of business and not producing any quality amplifiers in 2006, 2007.
Needless to say, I have made mistakes transcribing my few serial numbers and my hat is off to you for the work that you are doing. Best wishes.
Marc
