2017 Sansui Serial Number Database

Here are some stats from the April batch.

632 Serial Numbers Posted
After removing duplicates there were 596
504 new serial numbers added to the database bringing the total on file to 37,612.

Here are a couple that fell out of the process:
CD-X501,608066639,archiwum.allegro.pl CD-X501i?
TU-X501iL,617079093,marktplaats.nl Can't find the “iL” model

This one conflicts with an existing serial number
R-30L,830030455,archiwum.allegro.pl conflicts with AU-417 830030455 entered 10/31/23 from Facebook Australia. Can either of these serial numbers be confirmed?

Here is a really good example of what I've been calling a 5 stack. I found this on auction.net when looking for an example of a D-E750 cassette deck. Not only does this stack include that cassette deck, it also has the
Turntable "P-E350".
Equalizer "G-E750".
Synthesizer/Tuner "T-E550L".
Stereo Amplifier "A-E550".
Double Cassette Deck "D-E750".
Compact Disc Player "CD-E750".
Remote control + stereo rack.

The whole "kit and caboodle" sold for 64 euros. Do we want to clutter up the database with "throw away" away plastic components?

Hi AK,

My first post but I have been lurking a while!

I also have a AU-6900 but it has no serial decal, if anyone has ideas where a serial may be located internally?

I've never encountered a serial inside. There would be no need. There is one on the unit, on the box and on the warranty card. So I've been told... I have seen many units with the serial missing and just some glue residue left.
 
I have a similar model where the serial number sticker has recently fallen off and lost. Fortunately I made a note of it, made what could pass as good copies and put them on my amp. The stickers on the AU-5900, 6900 and 7900 were placed on the heat sink just under the rca inputs. It gets hot there sometimes and I suspect the sticky on the tag was cooked off. As PE9ZZ says there was one on the original box and/or the warranty card. The amp was made a decade before you came along so I guess you cannot be the original owner (if you're 38). If all else fails, there is a slim chance that if you bought your unit on certain sites such as Canuckaudiomart.com the ad was archived, and if it had the serial number then, it might show in a photo.

This is an image from an archived Canuckaudiomart,com ad. An AU-6900. I show it to indicate where the sticker was originally placed.

I will need to go back and check.
Edit: It is CD-X501i (with "i")


It is TU-X501L (no "i"):

Stupid "i"s...

I deal with this almost every month. Getting the damn letters straight can add hours to the upload process. It wasn't an issue until the last days of Sansui when they were churning out dozens of model variations.

Thanks @Monicker1. I'm certainly not the first owner. Just polling ideas from the crowd that may know more than I. Previous owner/s had removed the serial at some point. I noticed that someone had engraved a 9 digit number on the heatsink but understanding how sansui serial numbers usually apply, it doesn't seem to be a legible serial number, starts with 632.

I'll hazard a guess that 632 is the first 3 of a 9 digit Cdn Social Insurance Number (if it was originally purchased in Canada.) I think folks on the West Coast start with a 6 or 7. We on the East Coast start with 1. I bet the original owner has passed. Our collection of AU-6900s show the model was made between late 1975 and mid 1977. Unless you get extremely lucky, that is where the trail stops. We do not have a database of internal parts' dates, nor are we likely to know if a design modification can identify the range of time the unit was made. But it is a nice amp with loads of features and well regarded. As is your other equipment. So enjoy and look after them.

I stumbled across these serial numbers when I was looking for C-2301 pictures for a thread about Sansui logos here in AK. I was looking for a C-2301 with a silver face plate but I couldn't find one. Anyway, all of these serial numbers are missing from the database.

When I was filling those serials in excel, I was stupid enough not to fill the source as well. So two of them have a source indicated as "internet". It's entirely up to you, Pete, whether to accept them or reject them.

One C-2301 is from August 1989 and two B-2301 from September 1989. I didn't know C/B-2301 were produced as late as this. B-2301 was not B-2301L model according to the rear panel.

Indicating "internet" is fine. The biggest reason for the source information is if I need verify something with the serial number or unit. Occasionally, I need to confirm or clarify something with the unit or it's serial number. I use it to find the listing for the unit. That way I can take care of the question/verification without kicking it back to the person that posted it.

Many of the members that post the serial numbers for their collection like to have there username tagged to the serial number.
