Cool, My SX-1050 was one of the first ones then. Manufactured in August of 77.
Thanks for the info!

:scratch2: :scratch2: :scratch2:

SX-1050 started in 1976.
My SX-1050 has the Number. WI2900637M (E-P)
So it was build September 1976
 
Just checked the serial number on my SX-828..have not looked that close since I purchased it new!

I just learned that the unit was made July, 1973.
SG-3807625.
 
OK Strangelove,

How does one determine how many of the model were manufactured?

NYC minds want to know!
 
That would be some good information to have. I imagine that Pioneer may have kept such records, but finding who to contact might be an impossible task.

I have thought that if one understood the serial number formats, and had enough serial numbers, the production numbers might be derived.

Anyone know when the start of production was for the SX-1250? The one I just got was bulit in September of '76... :scratch2:
 
Dr. Strangelove:
Remember that you asked me about the serial# of my HPM-60's?
Well they actually conform more than you might think at a first glance as I found out today.

When you asked I looked at the first two letters which were MM...
Well, when this thread surfaced today I went and had a second look and MM is followed by YH which conforms better to the probable date of manufacture.
So it begins MM - YH
 
This is a very interesting thread. That would mean that my FM-B101 (S/N JL 13112) was manufactured in Decmber, 1963. And it still works - with the original 8v Dial lamps! :)

Pioneer SX-737, 110v Model, but somehow crept into 230v land.

Serial #: WA3954868T, which makes it January 1976 model.

Aaah, but you did help me! You were very helpful with the schematic and I was able to send some photographs of a beautifully working unit in exchange for your kindness :)

This tubed mono unit simply sounds GREAT!

You know, entering those advanced years is causing numerous problems for me. It looks like I can add memory loss to the list now.

But, I did not have the catalog photos published, so the net result is good.
