Since the new owner would have likely removed this tag immediately upon arriving home, I’m amazed that the one in the photo has remained intact since mid-1968!
Along with dating amps by serial numbers, we were interested in determining production totals, if possible.
Of course I tended to hurry more when they were there, and I would fumble more, too.” Another really interesting fact was that he recalled that the eyelet boards were loaded/wired/soldered in Mexico!
“I remember the circuit boards were pre-made, from Mexico, easy to screw into the chassis. When we had filled our cart we'd wheel it over to the Chicano chicks.
I remember two 'suits' from upstairs standing behind me occasionally doing time studies.
They actually held clipboards and stopwatches to measure how long it took for me to attach various parts.
Although his job was somewhat limited, his recollections provided some really fascinating insights to how the amps were built.

I promise the tables will still be there after you finish reading.
