So if the number on your speaker is 220947 it will read as follows; 220 is the Jensen manufacture code, 9 will be the year and 47 is the 47th week of the year.
The problem is the number 9 does not determine which decade (i.e. To determine the decade the speaker was made try to base it on what year the amp was made that it is mounted in.
Eventually, I thought, I'll get a rough idea what the highest and lowest s/ns were.
Subtract one from the other and I'll have a rough-cut figure for how many were made. PRII owners were kind enough to start sending their serial numbers in.
Now if it’s a blackface amp, it’s a safe bet that 6 means 1966. This code can be found on the power transformer, output transformer, choke, and reverb transformer.
They are all usually within a few months of each other.
So if your blackface amp has a date code stamp of OB, it was made in 1965/February.
Then the terrible truth dawned on me: they WERE all mixed up; Fender had decided to change their 35-year-old system of serial numbering so that, starting in 1982, every amp had a unique number.
I would have to collect data for ALL the amp types, just to work out how many were made of mine.
The first three numbers will be 220 which denotes the manufacturer as Jensen.
The next number is the year of manufacture and the last two numbers will be the week of manufacture.If it is a raw speaker then you have to make an educated guess.
