Sansui Serial Number Database Update

[Dan Schafer]

I really doubt that my model 2000 receiver would be from 1978.....maybe subtract 10 years or so. I'll look again, get a bright light and find a decent magnifying glass. Kind-a fun challenge and I'd like to contribute. Too bad Sansui used a paper label for that.

Dan:

You have a nine digit serial number which is correct and complete. Your 2000 was built in July 1968 on assembly line 01 and was the 9125th unit off that line for the month. Our sample of 2000s in the database indicate the 2000 was built between November 1967 and mid to late 1969. 9125 units sound like a lot, but many of them may have been small parts or components to be used in other equipment. That is our understanding of how the serial numbering system works. As only one digit indicates the year, there is a risk we might assume something was made in a decade earlier or later - that is two items could have the same serial number although they are a decade or two apart. That is an inherent flaw in the system Sansui adopted in 1965.

Well, I went outside in the dumb snow (for good light) & got a decent picture of the paper label. Also I had the wrong lens on the camera on 1st try. Daaa. I think this confirms the proper serial #. Safe to conclude there was no # originally printed in upper left? Hope this adds to the data base.
I enjoyed it.

So, 2000,018079125,dan Schafer. Want me to enter or will you (LBPete) do it? Correct format?

 

[Dan Schafer]

Gosh!....who would have thought I would be starting Kindergarten in 1968 in 2 months when that receiver was manufactured. Little older then I thought.....makes it cooler. As found, Had, metaphorically a "gold crowbar" across the power supply and all power transistors were emitter to collector shorted and unit was moisture (flood almost) damaged. Put aside to get a replacement power switch after 18 years. Now I'm retired and getting back to unfinished projects. Hope it still works after the repair 18 years ago, will bring up on a varaic. Will be posting my progress on the "Exclusively Sansui" Forum if anyone interested.

You have snow in Cleveland?? Just kidding. We have a little where I am in Nova Scotia but nothing like you near the Great Lakes. We will be interested in your progress. It sounds like a lot of work to do.

I was about to start grade 3. In July 1968 I was in a little rented cottage for three weeks at Cape Cod MA with my sister, visiting our grandparents who lived near Boston. I can still remember the address of that place. Sansui would become a part of my life two years later when my parents bought their first true Hifi system. And I have grown up with Sansuis since then.

Pete will have your number as you have entered it above. Thanks.

I have it. Thanks. Definitely 1968 not 1978.

Thanks Pete!

Your G-8700DB was built on production line 81 in March of 1980. It was the 153 unit off that line that month. Line 81 was also building G-9700s, G-7700s and G-6700s that month.

G-3500, 819022568, jimstl99
AU-7500, 834010672, jimstl99
Thanks again.

The G-3500 was built on production line 81 in February 1979. It was the 2,568th unit off that line that month. Line 81 also built G-8000s that month.
The AU-7500 was built on line 83 in January '74. It was the 672nd unit off that line that month. Line 83 was busy that month building AU-6600s, AU-555As, AU-505s and AU-2000s.

Thanks for posting.

Sorry, I'm new to this type of forum software, I don't know yet how to size the pics.

 

[LBPete]

@Tins, no worries, thanks for posting. Here's what I can tell you about your serial numbers.
Your AU-101 was built on production line 02 in October 1970. It was the 95 unit off that line that month. This turns out to be a very unusual serial number. We only have one other AU-101 on file built on line 02. It's also the earliest AU-101 on file. Thanks for posting the photo of the serial number. It verifies the serial number is not an "outlier."

The AU-222 was built on production line 24 in December 1968. It was the 272nd unit off that line that month. It looks like Line 24 was only building AU-222s that month.

Your AU-555A was built on production line 58 in July of 1971. It was the 797th unit off that line that month. Based on what we have in the database, Line 58 was only building AU-555As that month.

Thanks again for posting.

Thanks, Pete. I picked all three of the Sansuis in a job lot with another 101, many moons ago. Maybe I kept the right 101..

I've updated the Sansui Serial Number Database. It had not been updated since January 2009. I've compiled all the serial numbers posted in the database update thread.

The updated Sansui Serial Number list is now resides in the Digital Docs forum. You can get to it directly by clicking on this link: Sansui Serial Number Data. When clicking on this link, the pdf file will appear in your browser's download folder. You may need click on the browser's download icon to see it.

The database is extremely useful to determine things like the time frame units were built and the approximate number of units built. The more serial numbers collected, the better the data.

Please post your serial numbers to the 2017 database update thread located here.
When posting serial numbers please use this format: Serial Number, Model, AK handle. Like this: AU-919,220031540,LBPete. This format lets me cut and paste a list with all the data that can be uploaded into MS Access. Otherwise I have to reformat the data into this format. The commas are very important. They tell access to skip to the next field.

Lastly, please double check your serial numbers after you post them. There are a lot of decoding errors because the serial number don't follow the correct date format or the number of digits is wrong. Most equipment is 9 digits except speakers and some other oddball stuff. The 4 and 5 digits must equal a month designation.

Is there also a list with the SS 20 headphone serial numbers?

 

[LBPete]

Hi @16Horsepower, welcome to AudioKarma Exclusively Sansui. We have the serial numbers from 7 SS-20 headphones in the database. These headphones use a non-standard serial number format. It does not contain a discernible date or production line code. All 7 can be viewed in the monthly database report which can be accessed by following the link in the quote you posted.

I have a whole bunch of Sansui serial numbers from units that I serviced. Should I post them here to add to the database?

 

[LBPete]

Sure, you can post them here. Please use this format: Model,Serial Number,User Name. For example: 8080DB,817021234,Namlook No spaces, just a comma to separate them. I process hundreds of serial numbers each month and this format allows me to copy and paste them into a word doc.

You can also tag a note to the serial number by adding a comma after your user name. A typical note would identify a Japan marked model, JDM or single voltage model like 117V or 220V.

If you want to get into advanced serial number trivia, we track "T-tags." Sansui used contractors to build many units. These were identified on the ID plate with T inside a circle, the "T-tag." In some cases the T-tag will also have initials like SOC adjacent to it. You can report a T-tag by adding a coma then T-tag. 8080DB,817021234,Namlook,117V,T-tag

All valid serial numbers are welcome.

Picked this up today. I know it's not high end, but the label on the box says Sansui..FR-1080 TT. No, it won't live on top of the Perreaux.
