Next, we want to take out the E-MU's front panel printed circuit board.

Start by removing the knobs from the volume and control pots using an allen wrench.

Then remove the control nuts and flat washers from all the pots.

All the pots must be loose for the Printed Circuit Board to come out.

Finally, remove the knob and hardware from the data wheel.

Now, position the top panel upside down as shown here.

The Last Page of this story explains how to separate the top panel from the bottom shell.

Prop up the panel on each end by an inch or two so the protruding pots and buttons don't hit the workbench.

This is especially important when reinstalling the PCB.

Next, remove all the brass screws that hold down the Panel PCB.

Then you can then lift out the PCB and flip it over as shown here.
