2017 Sansui Serial Number Database

@LBPete: sorry, I never bothered over T-tags, but just have read some few pages of this in this thread.
Is this a t-tag? Because then I've seen one first time for a long long time.

This would be something like
AU-999,serialnumber,kleinanzeigen,,T-tag
as a string for you ? Means with double comma separated, as it isn't a JDM-only machine as a different section of the backplate shows again the fuse as 100V~127V - 4A, 220V~250V - 3A.

Yes, that is a T-tag. Thanks for asking. It indicates the unit was produced by a contractor. It may or may not have initials like SOC or other identifiers with it. Please record those as well. The database has a separate field to track T-tags. AU-999,serialnumber,kleinanzeigen,,T-tag is the exact correct protocol for the data if there is nothing for the "note" field. The two commas to skip a field when importing that line of data. To include like the model variant, please list it like this: AU-999,serialnumber,kleinanzeigen,JDM 100v,T-tag.

That ID plate indicates it is a Japanese Domestic Model (JDM) with single 100v input. I don't know why the fuses are labeled differently but my guess is the back plate of the chassis is universal for all variants and the ID plate identifies the particular variant.

I'm starting to see patterns with these T-tags. They seem to be more prevalent on certain production line designations and don't appear on others. Unfortunately the T-tags haven't been reported consistently and I just started tracking them a few years ago so I can't say for sure that all units built on a particular production line were built by contractors.

Thanks Pete. I checked, but there are no further markings like "SOC". So I add it as JDM 100V,T-tag as you suggested with the next update. Cheers!!!

@Work2do, thanks for posting, nice job on the 661 recap thread.

@Pete, I wasn't the recap thread contributor, but I'll most certainly be referring to it. I have a ton of vintage HiFi gear of many brands I need to service. However, due to the amount of information and support on Sansui here at AK, I'm leaning toward starting the new year with the 661.

I'm more of a mechanic and have been successful servicing record changers and turntables without many electronics in the equation. I recently invested in some tools, Hakko station, Fluke meter etc. Have been watching some videos and reading schematics in order to gain some skill in servicing my own gear. Speaking of gear, I scored a QRX-5500 to add to the registry. It's been pretty neglected, but it's all there except the Mic level knob and think it would be pretty rewarding to see it earn a spot on my rack !

Will add a couple photos later today

Hi Sglaw461, thanks for posting your serial number. Your 7000 was built on production line 22 in August 1971. It was the 295th unit off that line that month. Line 22 was only building 7000s that month.

PLEASE, no question marks in serial numbers. They are just too easy to miss when I'm uploading a lot of serial numbers. If it's hard to read put in your best guess with a note that it's hard to read like you did with this one. The 8th digit looks like an 8 to me so I'll put it in that way. The notes and T-tags you listed are perfect.

I found that the TA-500 has a non-plausible outlier in the database (038010027, expected 039010027). There were no serialz in the Catawacky this week.
 
There is a note tagged to that serial number saying the 8th digit is questionable and all are hard to read. I'm going to delete this one rather than make multiple "corrections".

Hi Pete, Merry Xmas and Happy New Year to all on the Sansui Database project and special mention to you Pete for the great dedication and effort expended.

December 2024 run attached: A couple to note: a new T-tag [for me] uncovered "MINE" and a blurry one

Merry Christmas and Happy New Year Bruce. Interesting T-tag, MINE seems appropriate.

Good confirmation, That's how Bruce reported it too so we will go with it.
