| The display on the left has been adjusted to '61d' Note that in the photo, the light caught the moved resistor, - it is not a solder blob across the pads, but the edge of the resistor catching the light. | The display on the left has been adjusted to '61d' Note that in the photo, the light caught the moved resistor, - it is not a solder blob across the pads, but the edge of the resistor catching the light. | ||
