ENGINEERING MADE EASY

    Radio Engineering is not as hard as
as people  would  lead you  to believe.
Almost  all  problems can be  traced to
a defect  in the circuit board.  All of
the  standard  circuit boards  have the
same style components.
    A circuit  board  consists  of  six
parts.  The  transformer is  where  the 
power  originates. From  here the spark
travels  along  a metallic path  to the
various components on the  board, until
it reaches the outlet at the end of the
circuit. If anything stands in  the way
of the circuit, like a defective  part,
the  circuit is  destroyed, causing the
piece of equipment to blow up.
    The job of the  engineer is replace
these parts before the  electric charge
can reach them. This would be easy, ex-
cept the only way to test the part,  is
to  actually   run  power  through  the
circuit while you are working on it. So
you need to replace the parts while the
current is actually running through the
board, trying to  replace parts  before
the electric charge reaches them.
    With that in mind you need to  know
how to fix various components on a cir-
cuit board.
    The transformer never malfunctions,
so you can immediately rule out that as 
the part that need replaced. The outlet
at the end of the circuit board is also
something that never breaks, so that is
another item that needs no maintenance.
    That leaves light bulbs,  set screw
assemblies,  transistors, and  fuses. A
good engineer needs  spares of these in
his toolkit. When an  item such as  the
ones  described above go bad, they have 
a tendency to take on a reddish  color.
You will need to replace these parts by
the time the  electron  charge  reaches 
part. If the cherge reaches the part on
the board before it is replaced this is
what will happen.
    For the fuse, the  electron  charge 
back up into the main  unit, this  will
cause an intermittent loop of  power in
the main recoil mechanism, and the high
voltage surge will destroy the piece of
equipment.
    As for the light bulb, by not being
able to replace it  in time, the  extra
power races through the  board and soon
catches up with it's back end. This can
and usually does  cause a  fire in  the 
transformer flux-a-lator. When this oc-
curs the power loop causes instant shut
off of the main board, and the  machine
blows up.
    When a bad transistor is not  fixed
in time, a carbon build up on the ding-
us homper occurs.  When a dingus hopper
comes in contact  with  any  amount  of 
carbon, the  reversal  of the  magnetic
polarity of the lead lined copulator is
is  going to  occur, when  this happens,
you got a major breakdown.
   And finally the set  screw assembly.
In all piece of equipment, you have the
set screw assembly, what  this  does is 
to set the screw  to your  assembly. If
the set screw assembly is  even a mili-
meter of the  screw setting, then  your
entire assembly is not set in the right
screw mode. When this  occurs the piece
is not set, the assembly is not  assem-
bled, however the machine is screwed.
    This manual should help  you in all
tasks encountered in your role as chief
engineer of a  radio station.  Remember
if you keep the equipment  running, you
keep you job.
