5) Check that all switches are as squarely aligned as possible, then carefully lower the circuit board,
component side down, onto the switches.
Don’t let go of the board
after you have it settled on
the switches as the board will tend to rock towards you and fall off the switches.
6) To solder the switches, keep pressure on the board with your “spare” fingers placed in between
the two rows of switches and near where you are soldering. This keeps the board level and square
on the switches.
The next step is to install the front panel LEDs. In order to hold the LEDs at the proper and consistent
height above the board, use the front
dress panel as a jig.
Do not cut or prep LED
leads
until after soldering is complete!
1) Insert D1-D36 fully into the circuit
board. The anode of the LED is indi-
cated by the longer lead and the
cathode by the flat spot on flange
(for the specific LED in the parts list).
The cathode is closer to the top side
of the circuit board and the anode is
closer to the bottom of the circuit
board. You may want to prop the
PCB off the work surface as shown
to accommodate the long LED leads.
