2017 Sansui Serial Number Database
- Thread starter LBPete
- Start date
@Cubdriver, thanks, it will be in the February report available early next month.
@PE9ZZ The AU-7k7 only has eight digits. Usually I discard serials like these but this one looks legit. Ish.
It defiantly looks legitimate. It's interesting to see it is a single voltage EU model and the serial number starts with 85. We have 63 of them on file, all with 9 digits and none of them was built on line 85. I'm going to put it in with 8 digits. Thanks for calling it to my attention.

@Reidy12, PE9ZZ, Here are some serial numbers that got kicked out when processing last month's batch:
I can't find examples on line of either of these two:
A-M700,655099335,marktplaats.nl
SS+22,64001, Reidy12,ebay.com.au AUS
This one the serial number doesn't come close to the others we have on file. We have 17 examples on file and they all have conventional 8 digit serial numbers.
TU-70,RE10114NT,Reidy12,FACEBOOK Vintage Sansui Amplifiers
Also the AT series timer with 3 digit serial numbers are becoming troublesome. The serial numbers are recycled between model variations. Not sure how to best handle the duplicates.
I've been busy with a major home improvement project and I'm a little behind with some of this stuff. Hope you guys can still sort this out.

Hi Pete, see below:-

Maybe the real serial number is not in view elsewhere on the unit [on horizontal surface above the speaker terminals?] but the back panel sequence seems meaningful.
The AT series timer serials - I just find them!! Problematic if these are recycled among different series, I see your issue as no doubt your scripts are searching for duplicates...mmm
I trust the home projects are on track and meeting expectations

Re: the TU 70. I have looked at about a dozen of these tuners online.
The serial numbers seemed to have been stamped with ink on the chassis on the older units - near the power cord. The later units had the yellow sticker we all know and love placed just above the power cord. Many of those stickers have fallen off over the years. TU-70 production run started in 1964. Early units had a half skirt mesh covering only half the opening. Later units were fully enclosed. All the stamped serial numbers that I have seen begin with S followed by another letter being not greater than L. (the 12th letter of the alphabet). I suspect your find is an earlier model. I have seen detailed pictures of the inner topology of these tuners and there is no sign of a serial number anywhere inside the unit.

@cnyel1967, @PE9ZZ, @peterott Thanks guys, got 'um!
@Reidy12, @Monicker1, Concering the TU-70, we have 16 of them on file all with conventional serial numbers. It didn't occur to me that their production started before the paper labels. I'll put it in.
Bruce, it's a SS+2, not 22

Hi Pete
I just went ever the dates of some of the oldest equipment we have on record in the database. I hope you find the following interesting:
Notes:
Pre 1965 Date Attribution.
Correction: AU-101, 514051992, Page 137 of Database should be 1974 not 1964.
This is the only date in the database attributed to 1964. (As mentioned in the TU-70 notes above. We have little in the database pre 1965 when the paper labels which were more standardized started to be used.)
There is also June 1962 Dating of a Sansui 500 receiver (page 36) which is impossible since the first 500s were released in late 1963. Likewise the 500 listed above it is probably an error (February 1969) because that was too late for the 500's run. I am wondering if it is actually a 5000. But I cannot prove it so let it stand.
These are the only two entries in the entire database which have been deciphered as being prior to 1965.
1965 Attribution.
Of 71 entries with a 1965 date code, only the first few are in error. They appear on page 1 of the report as part of the 1000A Receiver
16073548 July, 1965 *Probably 1966
16052029 May, 1965 *Probably 1966
16040241 April, 1966 Okay
16038095 March, 1965 *Probably 1966
I have also looked at the Invalid date codes of which there are 530. I am looking specifically for those very early ones with the alpha-numeric type found on the oldest equipment. There is not enough information or data to hazard a guess as to how that system worked.
I have about 10 TU-70s coming at you before the end of February.
And for collectors there is a Sansui PR-330 from 1955 available in Texas on Ebay I think. An AM (MW) only receiver. It is cheap, for repair or show.
Really really old!!
No serial number to be seen on this one.
Cheers
Ian

Oh crap, it's true...I'm loosing it, maybe the missus is correctBruce, it's a SS+2, not 22
Apologies Pete.
@Monicker1, Good stuff! I tried to quote your post but for whatever reason AK isn't providing the code to break it up and insert comments. So I've put my comments in red.
Pre 1965 Date Attribution.

Good eye, I've made the correction.

There are two 500s listed with 9 digit serial numbers. It's unlikely 500 production ran long enough to see 9 digit serial numbers. Looking at the 500 with SN 212060054, it's likely to be a 5500. Line 21 was building 5500s and QRX-6500 that month. There is no other production on line 21 with a year of 2 and a month of 06. I've changed it to a 5500.
The other 500 with a 9 digit serial number is SN 229023105. This one is likely to be a 5000. A lot of them were built on line 22 in 1969. I've changed it to a 5000.

You are correct. The second digit is the year in an 8 digit SN. I've changed them. Looking at the entry dates for these SNs and the AU-101 above, they were all entered at a time when the date code had to be manually decoded. Most of them were entered when I revived the DB in 2017. At that time I sifted through about 8 years of SN postings on AK that weren't cataloged.
I have also looked at the Invalid date codes of which there are 530. I am looking specifically for those very early ones with the alpha-numeric type found on the oldest equipment. There is not enough information or data to hazard a guess as to how that system worked.
I have about 10 TU-70s coming at you before the end of February.
I really depend on guys like you to find these errors. We now have over 36,000 serial numbers that were provided by countless reporters. Errors have occurred and will continue to occur. Thanks for finding these, and I look forward to the 10 TU-70s.

Fotosoup skills or not, these serials are too far gone to be decoded. I looked them up. Images like these happen often and I always skip them. Even Catawacky has its share of crap imagery. Most people either have no idea what they are doing or just don't care. Some post only one pic or none at all. Such is life...
The AU-919 in the middle is the easiest to read. I would guess it is 228070472 which would be consistent with the 919s we have so far. But the 4 could be a 5 which would be plausible as well. The other two are not even guess worthy.
PE9ZZ: Do you use " " quotations around serial numbers you are uncertain of? I think that is a good idea.
I would say that at least half of all equipment I see cannot be "harvested".

@peterott your serial numbers will be in the February report. Thanks
@Monicker1, The quotation marks ensure that leading zeros in the serial number won't be dropped. I import the posted data as text rather than numbers which also holds the leading zeros. I remove the quotation marks in the upload processing using the "find and replace" feature. A couple of clicks and they are gone.
If you have a serial number with a hard to read digit, please note which digit is in question. Like you have done with the 919 sometimes I can guess the digit looking at existing serial numbers. If multiple digits are in question, we should discard that serial number. Noting that the serial number is hard to read when there are conflicting serial numbers. It helps determine which one to drop or change.
