Driver Testing Error [resolved]

On page 65, IA & IO measure correctly, but at 32U I get 136VDC and the potentiometer on the board does not affect the reading. I turn and it remains. On 46U, I was able to adjust the pot to 175VDC. Any ideas?

Looks like you are missing the 4.99KΩ 1â„8W resistor in the R3 position on the A side of the board. Last step on page 56. That should resolve it.
Also noticed some of the joints might need a bit more solder too.
