Use the procedure outlined above to install D11-D15.
Once all the LED leads are soldered, cut the length a bit more. You may find that it’s
easiest to leave about 1/8” of length (perhaps as much as ¼” in some places).
Take some time and care now to make sure that the LEDs are perpendicular to the plane
of the board and as close to level as you can make it. This makes installing the controller
board into the front panel a whole lot easier.
Install the Last Four Capacitors
These capacitors are installed on the side of the board where you began assembly. We’ve
left them off the board until now to make it easier to solder the LEDs in place and to
prevent strain on the capacitors.
Be careful of C7, C8, and C13’s polarity when you install them. They are polarized
electrolytic capacitors. Make sure that the positive side of the cap, the end not marked
with the negative sign, goes adjacent to the positive sign on the silk-screen.

Fit the Controller into the Front Panel
This section is very do-able, but if you are tense or tired, please take a break before going
on. The LED’s must be precisely aligned for the controller to fit through the front panel.
This will take a little tweaking, but stay calm and it will work just fine.
