Driver Board Gottlieb System 1
New DRIVER BOARD for Gottlieb System 1 pinball machines.
Replaces A3 driver board PB00-D110 in Gottlieb System 1 games. This new board has several improvements over the original:
- Higher voltage rated transistors for longer life
- Logic level FETs for higher efficiency & lower heat generation
- Higher current rated ULN2803 replacing obsolete MPS transistors
- Simplified schematic using only one transistor type
- Printed component designators and connector functions
directly on the board.
Also, most of the component designators are the same as original so that the original schematics can still be used.
