Dating fender amp serial number
A little light Googling revealed serial numbers for a few other amps in the range - they seemed all mixed up together.
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.
Could Fender make so many PRIIs, considering they were making another 13 amp types in the range at the same time?
Then Soren in Denmark started showing serial numbers on his excellent Super Champ website, recently gone off the web - some of those numbers fell in between some of 'my' PRII numbers.

Fender don't part with that kind of information*, so as part of the website I developed for this amp's care and feeding, I put out a call for serial numbers.
Eventually, I thought, I'll get a rough idea what the highest and lowest s/ns were.
9 out of 10 did - many thanks to them for their trouble and good will.
I run a couple of websites making the schematics for these amps easily accessible.
As people download them, I'm hoping they'll respond to my request that they send me their amp's serial number for this project, and many do.
There are a handful of amp types for which I'm still running the searches because I have so little data (mainly in the solid-state range).
I would have to collect data for ALL the amp types, just to work out how many were made of mine.
Then I became aware of the amazing work Greg Gagliano had been doing since the 1990s - the summary of his latest results are here - and that his research stopped just before the Rivera-era. However for this range of amps at least, I reckon it's not just a policy of withholding company-confidential information. It's no criticism of Fender to suggest that they were too busy making great amps to keep records just so some amateur can use them thirty years later.
