Hello all,

I finally installed the second speedball circuit board today. All 4 readings are fine except for the reading for terminal OA on the biggest board. It reads at about 162V. All the LEDs are lit on both boards, but the ones on the smaller board are very dim (the ones on the b side more so than the A side).

Edit: I believe I solved the problem. Termianl 9 needed a little more solder work on it. Just for a double check, is it ok if the readings on the bigger circuit board for OA and OB are both around 105V?

105V on both is just fine provided your readings on OA and OB on the smaller PC board are below about 95V.
