I think the AU-555A is 820100265 because so far (as of June 30) we have nothing off line 82 in October 1970 (or 1980) higher than 1742. (820101742). So I don't think they got up to 6000s. To my eyes, your reading on the 881 is correct.
The AU-1100 was harvested so your clear photo of the AU-6600 wins.Pete -
Was the AU-1100 with same serial number from a member's private collection or was it a harvest? And are these database entries date listed?

Absolutely correct. The serial numbers can recycle every ten years. I'll add the TU-777 to the Duplicate Serial Number Table and it will show up in the September Database Report. I didn't realize the CA-2000 was ten years later. I thought they were earlier.Pete
Is it possible that both serial numbers TU-777,238020068 and CA-2000,238020068 are correct?
TU-777 is from February 1968 and CA-2000 from February 1978.
Production line 23 was in use in both decades.
Just wondering.
As has been pointed out, I was one zero short in identifying the model.Pete
Vast majority of AU-2000 units come from production line 83, one unit from 82, one from 50 and two from 01. And the latest units are from April 1974. It is very unlikely that one unit would have been manufactured in October 1975 in production line 21. So probably AU-2000,215100041 is incorrect and does not share the same serial number with AU-9900.

And there can be no decade gap here. It looks like this one is on Sansui.

I concur on both units.I think the AU-555A is 820100265 because so far (as of June 30) we have nothing off line 82 in October 1970 (or 1980) higher than 1742. (820101742). So I don't think they got up to 6000s. To my eyes, your reading on the 881 is correct.
I don't understand what you are editing. The AU-666 serial number is incorrect, none were made in either '66 or '76. It can't have a 9 as the third digit. Is the AU-D77X a new post?AU-D77X,604054476,Second Life Audio

The 666 came later and I did not want to create a new post.I don't understand what you are editing


An interesting conflict. The photo of the serial number on the TU-777 can be read clearly. We have a total of 66 TU-777s on file. Looking into production data, TU-777s were produced on line 24 during March and May of '69 but we have none on file produced in April '69. In April '69 Line 24 was producing TU-555s and TC-505s, not TU-777s. However, line 24 was producing both models in March and May so it is completely possible they were doing the same in April. We could have another Sansui duplicate.Stumbled across an unexpected trove of serialz:

There may be more conflicts. Did already weed out a few but doing this manually against a PDF is not really doable...
The TO-66 outputs is a good note to add to the serial number. You can add notes like that by adding a comma then the note. Like this: 5050,026060149,milo63,TO-66 outputs5050,026060149,milo63 TO-66 outputs
