Notes:
A rare 990DB. The 7th digit is a total mystery. (Photo)
If that is the edge of a serif then the digit is a 1 or a 2.
I am going with a 1. The other hidden digits show clearly
in other photos.

Classique S-900 new to our DB, photo. Not sure if it should go in.
Advertised as Classique "S-600" speakers on Ebay.com

QS-800, Looks like first digit is a 3 (photo)
but every unit in DB shows as an 8 so I'd settle for an 8

This SE-9 is a first on the 62 production line but tag is very clear (photo)

I have also lately been tapping into ebay because of the low number of offerings from my regular sources.

Hi Pete,

I was scanning the production run for the a607nra ii and from the numbers I am guessing around 200 units were produced each month in 99 with the possible exception of April. In April, if one took out unit 3142, it would also fit about 200 units.


In your opinion, do you think there was a larger run made in April or possibly an incorrect serial number?

I am trying to estimate how many were produced.

Thanks for you insight!

Thank you guys and Happy New Year. I'm going to start processing the December Serial number now. Anything posted after this post will be in the January batch.

@Monicker1, I agree with your best guesses. I need to develop a way to tag photos to serial numbers in the database. It should be possible in MS Access but I need to find out how to do it. That's a project for a different day.

@Gravelyguy, I'll look into that when I have a few minutes after the holidays. Stay tuned.

@RZ1, it all looks good. Thanks!

Hi Pete

Looks like a decade error on the D-95M cassette player. We have it as a 1970 era. It is a 1980+ cassette player I am sure.
Probably other decade errors in the cassette player D group as well.

Definitely seems at least early 80s. The overall aesthetic seems to match that of my 7900Z's, which was made in April 1981
 
Thanks, I made the change. That model was entered into the database prior to 2009 and every entry was wrong. The January report will have the correct decade.

Here's the December stats:

594 "raw" serial numbers posted including 16 duplicates in that batch

578 processed resulting in 492 new serial numbers and 5 new models added to the database.

Here are some that bounced out:

AU-alpha 607 MOS Premium,622050457,Reidy12,FB Vintage Sansui Amplifiers Equipment JDM,T-tag SANSUI-F
AU-alpha 907i MOS Limited,622050457,Reidy12,FB Vintage Sansui Amplifiers Equipment JDM,T-tag SANSUI-F
They have the same serial number

AU-9500,214000291,Reidy12,FB S-P,T-tag
The month digits, #4&5 can't both be zero

Overall a very clean month.

Got it, Thanks!

It would help me if you wouldn't leave a space after the commas. MS Access sees a space as a valid character. That adds a digit to the serial number making it a 10 digit serial number. The program kicks out non standard serial numbers at an awkward time in the process. I've been deleting the spaces but sometimes I don't see it but Access sees it clearly.

Thanks!

Could you do me the favour of reporting the total number of entries in the December report so I can check if it agrees with my count I came up with for the graph.

Thanks.

Decade Errors - D Series cassette decks.

I am looking at the 2009 database and realize that virtually all the cassette decks with a "D" prefix were set to the wrong decade of the 1970s where they are probably all 1980s or maybe into the 1990s. There are even a few in our DB allegedly made in the late 1990s 2000 period which I might doubt.

I believe the first cassette Sansui produced was the SC-700 around 1972, a top loader with the look of a late 60s / early 70s machine. Then the rest of the SC line followed in the mid 1970s as mostly front loading decks. Then around 1979 or 1980 they used the "D" prefix for their 1980s collection. If there are any Sansui Cassette Deck aficionados in our midst maybe they could help us out. I only go by the look of the unit and make a guess. HIFI Engine also has a number of decks pictured, some with dates which is helpful.

If you have time and are in the mood during these long winter nights, maybe you could make the adjustments. This is relatively low hanging fruit.

Thanks.

Another round of Sansui numbers pulled from shopgoodwill.com:
AU-G77X,624071654,shopgoodwill (somewhat blurry, but readable)
T-7000,655011664,shopgoodwill
SC-1110,248031661,shopgoodwill
8080DB,827092068,shopgoodwill (some numbers partially obscured- this is my best guess)

Yes, someone seriously donated a 8080DB to Goodwill. Fortunately, it is listed on their site as local pickup in the Dayton, Ohio region only, so at least it is spared from the sketchy Goodwill shipping.

Blurry numbers are attached here:

I'll take a look at the D series when I have a few minutes. There's actually a really good reference site called CassetteDeck.org that I can consult.
