EG&G Drawing #317113 for StrobeGuard SS-125 (OWL) & Original Trigger Control Board
This is an original factory schematic and was drawn on 3-23-1984 and had its final stamp on Halloween day 1984. There is a lot of written corrections, value changes, notes and also a relay diagram from over the years as things changed. The original EG&G designated type number was initially LS-165, however it was kept as LS-158, the same as the previous SS-123 and StrobeGuard IV models.
Two photos are also included with this post of an original EG&G 77-3262/D316999 Trigger Control Board from 1984 for the SS-125's.
