No letter, but starting with a "7" means it came from Tektronix Holland, NV,toggle quoted messageShow quoted text
Heerenveen, The Netherlands.
The last 5 digits of all of the serial numbers are sequential. I don't know
how they relate to the revisions of the manuals, and part changes, but I think
they are coordinated so that the revision ranges apply everywhere.

Hello Jon,My other 7A26s have this format SN, but this has no letter, 708058. I think its a late model, but see no IC date codes.The Readout board is probably marked 670-2310-09. Then both board versions were introduced at B251090. You need the -01 version manual for that, Revised SEP 1985. I think the ICs have 3-digit date codes, the first indicating the year (5xx pointing to 1985). Of course the plugin itself can be newer than the ICs in it. My 713121 is from 1986.
