Datasheet for the 2N5191 medium-power transistor, provided as a 217 KB PDF with an unexplained RE suffix. No manufacturer or revision is stated.

Filed under schematics, this 65.3 KB PDF is named only for the 2N5191 part number, so it is almost certainly a component datasheet rather than a board drawing.

Datasheet for the 2N5195 bipolar transistor, a 120 KB PDF filed under schematics. The name gives no manufacturer or revision.

PDF datasheet covering the 2N5194 transistor, 213 KB, with an RE suffix in the name that may denote a reissued or alternate vendor copy.
