Data East & Sega - PPB-1 A/C input and GND points - V1.0
This board provides indicators for the ~48VAC that is rectified on the PPB-1 board for the "High Voltage" coils. It also provides convenient Ground points for my other Indicator / Test boards.
Easy to Use. Simply remove the plugs from J3 and J4, and connect this board onto the J3/J4 header on the PPB-1. Then plug the connectors to J3/J4 on This board.
If The LEDs are off, don't immediately assume a bad transformer. First check F5. Of course if F5 is blown (charring present, and not just a 40-year old fuse that died from age) then check BR1
