Stage 2 :- Phones and Key sockets
The two jack sockets are
used for the key and the
headphones. They fit
right on the front edge of
the PCB. Both sockets are
the same type.
Fit them one by one.
Make sure that all the
pins pass though the
board and none are
folded over when you fit
them. The socket
MUST
be flush on the board when you fit them, if not they will not line up with the holes in the
front panel later.
Solder just one pin on each socket first, then
double check the alignment. When sure they
are correctly aligned and flush solder the
remaining pins.
Again after you finish soldering these cut
the pins flush with the board.
Now we can do a more interesting test on the board.
Now since a lot of the parts are preinstalled we can
already test the audio amplifier section.
Make sure that any off cuts are cleared from the work area.
Plug a set of headphones into the ‘PHONES’ socket and power (12v DC) up the board.
Again check that the current is less than 20mA @12v
