This board is a complete redesign of the ball trough opto transmitter PCB that is used in the following games:

WPC-S

The Shadow, World Cup Soccer '94

---

WPC-95

No Good Gophers

---

If your game is not listed above, please check here: 1S-X9T-07B 4 Ball Version

The above games use a different trough board than the earlier widebody WPC-DCS games. The large 2 watt resistors that commonly fail on the earlier boards have been removed to a separate board. However the circuit still uses a large amount of power.

The 1S-X9T-07B opto transmitter board brings all of the improvements of the WPC-DCS version to all late model Williams/Bally games:

Tapered PCB conforms perfectly to the space provided and is significantly stiffer than the original, reducing board flex. Larger traces and pads for better reliability and longevity. Better IR efficiency. The original design used about 280mA of power to drive the LEDs. By chaining the LEDs in series, not only was the current increased for more transmissive power, but the overall current consumption has been reduced to approximately 120mA! Visual status LEDs have been added to the reverse side of the PCB, allowing them to be easily checked from outside the machine! Two green LEDs show the status of the two IR LED chains. One red LED indicates power being delivered to the board.
