4.7 MOSFET Q1, R5

The leads of Q1 must be bent so that is sits neatly over D5. Bend

the leads FIRST, then insert Q1 into the pcb. You will find it sits

very neatly on D5. This lowers the profile of the overall board and

stops the large heatsink fouling your case. The switches will be the

tallest items on the PCB. This is shown well in figure 9 below. Also

install R5 at this stage.
