Partridge Date Codes?

[countdecibel]

I am The PROUD Owner of TWO (2) FL112s, serial #s 13008 & 13369, and am making this entry to help? clarify/add info to the "Partridge Date-Code" conversation. BUT...there's a problem. On the side (outside) of the chassis there's a small, rectangular sticker, 5/8" x 1 1/2", white, with Green lines dividing it into sections. It says, "Tested" with someone's initials scribbled into one of the sections, and there's a date, which reads: 12/2/7?. Yes, there's an inked "S" and part of it goes RIGHT THROUGH the 2nd # of the year. The partridges are #'d: H7578A (Pwr), and H7579A (Output).... My ph camera sucks, or I'd supply a picture. BTW, the components are "Top-Soldered". I hope any of this helps.
