2017 Sansui Serial Number Database

Thanks for posting. Your AU-719 was built on production line 22 in April 1979. It was the 541st unit off that line that month. In addition to your AU-719, Line 22 was also producing AU-919s, AU-D707s and AU-D709s that April.
Hey, don't beat up the new guy.

I don't want to make an issue of this, but I have been over the December 31st db on PDF several passes and my total is only 42,072. I would not bring it up if I was a handful off, but 106 is a bit more than expected. An error type I would be susceptible to would be something unexpected in the Production Date column.
For example "Invalid DateCode" was there with 792 Invalid Date Code(s) (Page 717, an Auto RX-70 Cassette Receiver) I could easily have missed that. If there are 106 irregular entries in the Production Date field I didn't see them. Are there entries outside the 1965 - 2006 range?
No worries and don't look for it, but it was just a curiosity.

HaHa, I checked, not that new and I'm sure Adaboy5 would be ok with a reminder AND I have seen your numerous posts lately reiterating same so waved the flag for you, all goodHey, don't beat up the new guy.

Thanks guys, got 'um!
The database says there are 794 lines with invalid date codes.

42,178 is the total in the database. Any discrepancy is either the algorithm that generates the report is missing some serial numbers or data is getting lost the conversion of the PDF file into a more workable format like excel.

Thanks for the serial numbers. As far as blurry SNs, errors in the serial numbers mostly turn up in two ways, conflicts when adding new serial numbers to the database or as "outliers" in the serial number range for that model. The conflicts can happen years after the serial number is entered in the database and I don't currently have a good way to to the serial number. So, if you need to guess at more than one digit, let it go, don't post it.
I need to develop the ability to tag photos to a serial number but I'm not there yet.

Wow, you struck a nerve with this one. 15 of these D series cassette decks were in the wrong decade. They have all been updated and will be correct in the January report. You may need to update your model distribution chart!
Thanks for finding them!

Correction: Our oldest item, the PR-330 from 1955 we have as HW-731 as a serial number. The output transformer's model number was likely HW-731 which may have been visible on the surface of the transformer, and not on the chassis. I don't have pictures of this particular find. The PR-330 may not have had a ser # or it was not visible.
"Meanwhile, Sansui introduced the first hi-fi output transformer FW-754 in 1952 followed by the HW-731 and the HW-733 that were for Williamson type amplifiers in 1954. In 1955, a new Series of output transformers, the CW-781, the CW-782, and the CW-783 were introduced. Sansui transformer reputation in these early days was like "Inexpensive, well built, and extremely reliable although looks somewhat unstylish."

Note that the last entry is not in the database but is a duplicate in my own spreadsheet. Its companion amp (from the same photo) is in the database so this one must have fallen between the cracks.
The turntable is a multivoltage one with no Japanese characters except the T-tag. Dunno if that is unusual.

Can't say what happened to the T-701XR. I did a forum search and that line of data didn't come up. It will be in the January report.
The "naked" T-tag is common on a lot of multi-voltage models. Nothing unique about this one.
Thank you Sir!

I'll have to pass. Still need to do marktplaats.nl and also still plodding through allegro.pl... 16 Months to go. The Wacky is done for this week but that is always only a few new entries. I now have 9 serialz waiting to be checked.
Not quite sure what to do with this information. I've contacted @Meade the member who posted it.

You spoke to @Meade when he first posted his PR-330 on Posts 98, 99, 100 and 102 of this thread (July 2017). He found no serial number upon close inspection of the unit at the time. Only the letters HW-731 written on the back of the owner's manual. It was apparently his piece and not a harvest. He also lived near you...
------------------------------------
BTW There is a guy in Arizona that runs a HIFI Vintage shop who had one of these PR 330s for sale.
(The PR 330 was released in 1955, but I don't know how many years it was available. Note as well it is only an AM - MW receiver.
I don't know when the ad ran, but more interestingly he said he had as many as 4 available at the time. He could be an AK member. Perhaps he could be helpful in seeing if any of the PR 330s he has seen have had a visible serial number on them
"Up For Your Consideration Is; A Single Sansui PR-330 Mono Tube Pre-Amplifier and Tuner. This is a very rare piece that I am fortunate to have several available (4 total as of the time when this posting was listed). Also see my PR-400 for sale in my store."
