□
Install the LED indicator block in the location
marked LED. Be sure to orient the part so that the
red LED lenses face toward the end of the board.
These will overhang the end of the board and fit
through holes in the end panel of the cabinet (if you
are installing in a cabinet).
□
If you are building the standard option of the kit,
install the socket for the solid-state relay K1. The
notch on the 6-pin IC socket should be on the end
closest to the connectors (the right side).
After soldering the socket in place, you can insert K1
into the socket. Make sure the notch on one end of
K1 corresponds with the notch on the socket.
□
If you are building one of the optional
configurations with the larger 4-pin K1 relay, bend
the pins 90 degrees to allow the relay to mount
horizontally. The pins or metallic area of the relay
should not be touching any other components,
although the epoxy part of the case may touch C1.
□
Check the board for stray leads, solder bridges or other problems and fix as needed. Trim all
leads close to the bottom of the board with a pair of small flush or diagonal cutters. This is
especially important if you will be mounting your UKA-3 in the aluminum enclosure.
Cabinet Assembly
To use the optional aluminum cabinet, first make sure you have trimmed all leads as
close to the board as possible. Test fit the board into the cabinet by sliding it into the
second slot from the bottom. Make sure the board can slide fully into the cabinet. If you
did not get the RCA connector fully seated, they may need to be re-positioned.
Make
sure none of the leads contact the inside of the cabinet
.
