Sansui Serial Number Database Update

AU-7900,217030210,Monicker1
TU-7900,026080300,Monicker1
T-80,840120950,Monicker1
AU-6600,836040296,Monicker1

From ads posted here in Canada. None of these are in the Feb 28th Database.
 
FR-5080S,417010667,Monicker1
FR-D3,619121557,Monicker1
TU-S5,431050889,Monicker1

I draw your attention to the dates of construction of the FR-D3 series. Some are shown to be made in 1970. But they would have been made a decade later.

Did you post these serial number earlier and I missed them?

Thanks, that's a classic "decade error." Sansui only assigned one digit in the serial number for the year. The macro that decodes the serial number needs a decade reference to determine what decade to assign to a serial number. Get that reference wrong and the program kicks it 10 years off. All the FR-D3 listed as 1970 should be 1980, I've made the change and reset the decade reference.

Ian, thanks for bringing this to my attention. We now have 1,551 Sansui models on file. It can be tough to get all the decades right.

I did not post them earlier.

I am adding to the database as you explained to me a couple of weeks ago that all information is desirable. At first I thought it was only for equipment that we actually owned. When I see a Sansui for sale I am now checking to see if it has a clearly readable serial number. (No guessing). I even take screen shots of those with strange numbers - as well as the label which gives the model number.

I then check the serial number on the latest version of your database. If it shows there, I discard it. If it does not show, I presume you don't have it. I can send a few up to you each month. I also double check to make sure I have the correct model listed as I note there are a number of variants.

I am mostly sticking with Canadian sources. And I am expanding my search outside of the AUs (my main interest) into more obscure products.

As I am both interested and retired, I have the time to do this. But I have to say even if we all did this full throttle, we would only capture a tip of the iceberg..

Cheers,
Ian
 
Good man! Your help with this is welcome. I appreciate you checking to see if they are already in the database but the program will automatically reject duplicates so you don't have to spend a lot of time verifying existing serial numbers. Please post them in the 2017 Sansui Database thread in the Sansui Equipment Database Forum.

Fantastic job with this database Pete !...
Here is some for you:
BA-202,108070023,Le_syd1961

the BA-303 number is not visible :(
AU-555A,831050980,Le_syd1961

there you are and keep it up !! :bowdown:
 
Great work there Sir LB Pete !

I have few numbers for your database:
BA-202,108070023,Le_syd1961
BA-303 cannot be read !! :(
CA-303,108070029,Le_syd1961
AU-555A,831050890,Le_syd1961

I tried to access your link but seems I'm not registered there !
Keep up that outstanding database ! :thumbsup:
 
Thanks for the kind words. I just tried the link in my signature and the link in the first post of the thread it takes you to. They both work for me. You can access the 2017 Database thread from the Sansui Equipment Database Forum at the top of the Sansui Main Page.

The monthly Database report is posted on the first Page of Sansui documents in the Digital Docs Forum. You can access that forum from the main menu.

Can you post a link to this? Your instructions sound simple, but I can't seem to find it. Which "main menu"? Thanks.
 
Thanks Peter. These links also appear in the first post of this thread. The monthly Database Report is a large PDF file, well over 700 pages long. When you click on the direct link to that file, your browser may not display it without clicking on the browser's download icon. It may then ask if you trust the source. Say yes.

When you open AudioKarma, it opens on the main menu which lists dozens of different forums. Digital Docs is one of those forums, just like Exclusively Sansui. I don't know if the Digital Docs forum is a subscriber's benefit or if all members can access it.

That said, using Digital Docs can be confusing. You have to click through a series of steps. When you open the Digital Docs forum, it lists threads like all other forums. The second thread from the top is titled "Here is the Database."
Click on it.
You will see a single post with the link to the database.
Click on it
Then you will see a menu with an alphabetical list.
Click on "Brand S User Manuals."
You will see a list of brand names starting with S. Sansui is on the right side of the first row.
Click on it
The Monthly Sansui Database Report is the first PDF listed on that page. There are links to all the various Sansui literature that AK has in it's Library
Click on it
It then opens a page with the actual link to the report
Click on it and that month's report will open.

Just a side note about the Digital Docs "Database." It's actually a library, not an actual database. It has no interactive functions like a true database.

Thanks, Pete!
 
Pete, I was distracted, or dragged by curiousity on another database, with the "Sansui - Years of Manufacture" and gave it a look.
It looks exhaustive but I could not find the BA 202 nor the BA 303 ...
Another point regarding the years mentionned on some units.
The AU 11000 (for example) is mentionned to have been manufactured in1975 1976 1977 1980 1983. Was the production was stopped in 78, 79 and in 81, 82 ?
Sorry for digression but ... just curious !...
 
Hey Pete, thanks for keeping up with this task. Please, include these pieces

Eight,210120428,toymanmsp
SC-3003,096020188,toymanmsp
TU-5900,026100176,toymanmsp
AU-5900,836050233,toymanmsp
AU-9900A,217040743,toymanmsp

Both the 5900 and the 9900A have been fully refurbished. ;) I thought the 5900 was awesome after the rebuild. However, I'm even more impressed by the 9900A beautiful piece of kit!
 
@toymanmsp, thanks, they will be in the April report at the end of the month.

There are a number of very old files posted by the previous host of the database before he retired around 2009. Those files were based on the serial number database at that time. There were just under 6,000 serial numbers in the database at that time. Those files are are full of holes because of the small sample size and errors that existed in the data. Those file should really be taken down.

There are currently almost 32,000 serial numbers in the database. Here's some current data on the models you mentioned:

BA-202; 14 serial numbers on file. The first one was entered into the database in March of 2017*. It looks like Sansui made three batches, July '67, October '67 and July '68
BA-303; 8 serial numbers on file. The first one was entered into the database in March of 2017*. Oldest on file is July '67 and the newest is March of '68

AU-11000; we have 80 serial numbers on file. Earliest production on file is January '75. Last production August '77. The 1980 and '83 dates are erroneous and are no longer in the database.

It's very easy to miss report serial numbers. When you add together printing flaws, dirt and smudges on the paper labels with poor quality internet images, 8s can look like zeros or 5s can become 8s. Is it a 1 or a 7? With the help of AK member @Peter lye we have been actively correcting errors when we can identify them. I just made these kinds of corrections with the BA-202 serial numbers.

* A side note, March 2017 is when I revived the database and input all the serial numbers that were posted between 2009 when updating the database stopped and March '17.

Hope this clears up more questions then it raises.

- Pete
 
Thanks Pete for this detailled explanation.
Of course my interest comes from my recent purchase of a BA 202, BA 303 and CA 303. This is again an amazing compilation, I repeat myself but I'm very admirative of the work you all done here !

Maybe a little oservation that will help updating a bit the base on this last one as the serial database shows 3 reported from 1973, 6 from 1967 and one from 1968 but there is only one year specified in years of manufacturing (1967) ...

Maybe worth crosschecking databases could help getting them more accurate.
 
Just to add what Pete had mention > printing flaws
below is A classic example of printing flaws on BA-303 SN 577200028 which we had corrected to 577020028
u.jpg

https://www.hifido.co.jp/sold/13-73175-80569-00.html?LNG=E

After reporting 2 more SN of BA-303, I came to A conclusion that the above 577200028 had the month 20 stamped wrongly.
The tech @ the factory must had mess up the 1 with the 2. so I leave to Pete judgement call , > 577100028 instead of 577020028 presently.

below the last 5 do look like AN ''6'' from far

Is the database seeing any change in the rate of registrations? Increase, decrease, same?

I don't try to track that. 90% or more of the serial numbers posted each month come from a small group of guys "harvesting" serial numbers from the internet. How many numbers are posted each month varies widely. There have been months when 2,000 or more serial numbers were posted and other months when the total is just 150 or so.
