Playfield Electric Company Display
The part number for the 5x7 "red only" LED blocks is GMA8875C made by On Semi/Fairchild. The part is no longer manufactured and is obsolete.
An alternate part that Stern used and is labeled on the side of the block is LTP1557AC which is made by LiteOn. The datasheet for this LED block can be found here.
The resistor that appears to be a "hack" was a factory modification and is shown on the schematics.
