Pioneer Dates of Manufacture

[YamahaFreak]

Does anyone know of a method to tell the age of Yamaha components? :scratch2:

 

[VU Meter]

Anyone know when the start of production was for the SX-1250? The one I just got was bulit in September of '76... :scratch2:

Don't know, but mine was built 10/76.

 

[fede_vr]

just checked my "new" Pioneer gears and found out that both the PL-620 and the SA-510 have the diamond with the EP mark on them..
Serials are :
PL-620 : BE 139145 that reads as May 1981
SA-510: AH 9431372F that make it a August 1980 one
DrSL : lots of +K for the great job on this site.
Greets, Federico...

The SX-1250 ran from 1975 to 1978.

To determine the date of manufacture of your Pioneer component, look at the serial number. The first two characters will give you the year and month of manufacture. The first letter is the year, the second letter is the month........Doc

Thanks for the chart, Doc. I have an SX 535 that I wanted to date...very interesting. It's a VE..., so May 1975.

For what it's worth:

TX840............DH3607571M
SA1040..........DH3603433S

Aluminum tags with aluminum rivets.

I bought this "matched set" on ebay. I assume they were originally purchased together. From the list above it would seem to be 1983.

 

[Dr. Strangelove]

Thanks for the info.

I have noticed that some of the various tag styles were used at the same time.

Finally look at my Pioneer SX 1250 serial # and it was built in Dec 1977 -----must of been one of the last. They were built from 1976 - 1978.

The number is XL3630569S ----- anyone out there know how to decode the rest of the numbers.
Thanks James

Thought I'd add my 'new' sx-1050 receiver. This one says VK3900080M

Now according to the chart this means November 1975. Thought these came out in '76? Made in Japan of course. Thanks for any info on this.

 

[Steve 1050]

Here,s one for ya; no serial no. on my SX 1050. I've looked and there is no serial no. on my reciever, no tag, nofoil sticker, nothing!

Well...I wonder why someone would remove a serial number? :scratch2:

 

[Steve 1050]

Odd to me also, however as this unit os over 30 yrs old I'm not really suprised. Things happen. BTW I purchased this at a "Flea Market" for 30 Bucks.

 

[jimbofish]

Anyone see a pattern? Look at the two DT-500s (both from Oct 1980). Hard to see a pattern there. We can come up with theories, but without more data, we would be merely guessing at how the numbers were derived.

Doc

Now that you've got a sizeable amount of numbers, you could enter those numbers into a spreadsheet and then do some sorts and filters. If there is a method to the numbering system, it should show up.

I've checked all my gear and all have the <EP> mark also (lone one being the PD-7010 CD player). I was in the Air Force from 79-90, so I'm wondering if any civilians were buying pioneer gear in the 70s - early 80s?

 

[Cool_Manchu]

First and foremost, thank you Dr. Strangelove for providing the information for us to find out the date of manufacture of our Pioneer rigs.

I have an SX-1250 and my serial number is WA3901390M

Given this, I realized that my SX-1250 was made in January of 1976. So I guess I have one of the first ones off of the line.

Pioneer cs-63dx

I am new to this forum and grateful to have the opprtunity to access it's broad resources.

I recently bought a pair of Pioneer CS63dx speakers. One serial # starts with TA-WE (assume this one was made in 1973) and the other one is NA-WA. Is it safe to assume that one starting with NA was made in 1967 or was it made by another company as mentioned by Dr Stranglove in the the quote below?

Please let me know & thanks for any replies.

To determine the date of manufacture of your Pioneer component, look at the serial number. The first two characters will give you the year and month of manufacture. The first letter is the year, the second letter is the month. For example, taking into consideration the age of the equipment:

ZA would be 1979, January
YL would be 1978, December
KK would be 1964, November

W	1976	2002
X	1977	2003
Y	1978	2004
Z	1979	2005

Not all Pioneer components followed this rule. For example, the Pioneer SE-700 headphones had a two letter prefix, but did not follow the table above. For these components, it is rumored they were made by another company, possibly Azden or Stax, for Pioneer.

But, generally speaking, most all of Pioneer's components from 1954 followed this table.

Thanks a lot for this post... it's helped me determine the year and month of production of my Pioneer PL-707 TurnTable

Serial Number: EA 17191 H so January 1984, right?
