I came across this today and thought I might share it with the group:

Dating your Vox amplifier

Because the Vox name has been used by such a variety of companies in
different locations, no lists of serial numbers are available. Even so,
certain characteristics can help narrow the date of manufacture to within a
year or so. These characteristics can be applied to most amplifier models
prior to 1985.

This list comes from The Vox Story book.

I cleaned up my tab for Sonny Boy's Help Me and made it into a short book. There's a Kindle version for 99 cents, and if you buy the paperback you get the Kindle free.
