2017 Sansui Serial Number Database

M Un said:
You are right, it is not a serial number.
This is what Google Translate says. So, it looks like it was a demo unit used by Sansui, unless someone speaking Japanese corrects me.

Like Pete says, you have a pretty rare piece there.. More than likely a pre-serial production sample identified by the Management number (instead of serial number) as to date and sequence.

Interesting. Quite a rare find.

craggd, I have your serial numbers.

It might be a good idea to record these ones as well to start a database of Management numbers in addition to Serial numbers. I'm sure it will be a relatively short list, but might prove of value for comparing product design changes of each model. A question would be, "was a Management product different than the first or early Serialized production models?".
 
How do you propose to record it? There is no easy way to catalog it in the existing database without a serial number.

Since they'll be pretty few and far between, you could use perhaps a spreadsheet to start. I'm far from a computer genius though. If any differences are discovered, then a notation, or a reference could be made somehow as an addenum, or just made into a sticky thread. But of course it would also depend on any techs taking notes to possible differences found, if any. I just thought it might be interesting for a more complete history of Sansui.
 
A few more acquired late last year

I can create a separate table in the Database for prototypes and tag a photo of the paper ID tag. Since there is no serial number, it would have to be listed by model and the AK user name of the "reporter."
Yes, they will be few and far between. Right now there's a pool of one.

Not sure why the number of digits should be different on these otherwise identical speakers...
It doesn't appear to have been erased or torn...

Most Sansui speakers have an 8 digit serial number. We have 4 examples of the SP-X9000 on file and all of them have a 9 digit serial number. 3 were made on line 90 and one on line 95. Your speakers were made on two different assembly lines. You can also see that the serial number tags look different. That may indicate they came out of different factories.

The speaker produced on line 90 was built in August '78, the one built on line 97 was produced in October '77. Usually, pairs of speakers are produced much closer together, like @antpaubarcar's SP-7100s above. They were produced 3 units apart. There is a good possibility that yours were two "orphans" mated together some time after their original purchase. It's also completely possible they just sat in a warehouse for a prolonged period of time and new and old inventory was mixed together.

We may never know their true history.

Thanks for the useful information.
My speakers have become a little more mysterious to me :)
