Under Loud's new ownership, Ampeg switched to a different s/n system in 2008:

The digit after the year is decoded as follows, per Hodgy at Ampeg:

"...our most recent date codes do a letter for every 2 week period, so A= Jan 1-15, B= Jan 16-31, etc."

in that pic it's only a 16 digit serial

My recently arrived PF350 has the number "0" as the 12th digit in the serial number. The only letters that would make any sense in that coding would be the 9th and 10th, which are "F" and "R". Which would mean mine was built in september 2013. But mine is a European model, with 15 digits in the serial number.

Look at it this way: String of numbers indicating the item (or actual item, like "SVT7PRO")----> then 4 letters, indicating place of manufacture (1st 2 letters) followed by year and month (2nd 2 letters)---->the number "off the line".
It's not necessarily always going to 16 digits, or 17 digits, or even 12 digits (as in the HB-15N. It just happened to be that many digits the day that they made that graphic (wrong or not!).
So, semi-official word is: 3rd letter from the left of the group of 4 letters after the model number but before the 4 (or 3) serialized number is the year.
I hope this is extremely confusing. I mean, not confusing at all.

Thanks Hodgy!

Yeah my fridge had the 0 instead of a letter too. I think its a 2011-2012, would you be able to tell me the year if I posted the SN hodgy?

Confusing enough! My brain doesn't half hurt trying to follow the goings on of serial number nomenclature

Yup!
Just be thankful that we publish our nomenclature at all, many companies do not, and as most of you that have had some experience with 70's era Ampegs, you know that during that time, it was all "serial number, Schmerial number".

Thanks!

 

[Forrrest]

Not all 2008 was on the new system, I have this one that is year U (2008)

But in general now I got all my stuff sorted. and I'm glad I'm now aware of the new system that started in 2008.
Thanks!

Am I correct in assuming my 410HLF which has Made in China on it is 2009? Serial number is EDADV05358.

That sounds right, although it looks like they hung onto the old serial a while longer than 2008
