Wrap
Don’t solder the components as they
go onto the eyelet board . Instead
wrap all the parts onto the board,
bending their leads tightly so the
parts stay in place without solder .
Don’t think of solder as glue
Good mechanical connections make
good electrical connections . Solder’s
job is to finalize an already good joint,
not to hold the parts on the board .
Inspect
When all the parts are in place, stop
and inspect . Go back over every step .
Careful inspection is the best way to
make sure your amp works the first
time you turn it on .
Make the specs visible
Attach components with the specs
facing out so you can read them . Many
builders also align resistor bands to
read in the same direction .
Solder
Solder each connection point only
once . Reheating to add another part
makes a messy, faulty solder joint .
Use the soldering tips below to get
professional results .
How much insulation to strip?
With plastic insulation, strip 3/8" from
the wire ends . Push-back wire works
best when you strip away about 1/4"
of the cloth wrap .
How to wrap and solder the eyelet board
Put the lead through
the eyelet or lug
Bend it tight against
the opposite side
Solder after
all the parts
are in place
Trim excess wire
Tips for great soldering
n
Wrap the leads tightly for good
electrical contact before soldering .
n
Melt a small amount of solder onto
the tip of the iron (“ tinning ” the iron) .
Hold the tip against the connection
until the connection reaches solder-
ing temperature . This should take just
a few seconds .
You should also tin component leads,
like coating multi-strand wires to help
the solder flow for a more solid joint .
n
Keep your soldering tip clean by
wiping it often on a damp sponge .
Also keep it tinned by occasionally
melting a little solder onto it .
n
Feed solder to the connection, not
to the iron . Stop feeding solder once
the eyelet is filled . Keep the iron on
the connection for a second longer;
this pause gives time for all of the flux
to cook out of the joint .
n
Don’t blow on the hot solder or
touch anything until the joint has
cooled completely . A good solder
joint is shiny — a sign that it was left
to cool undisturbed .
n
After the joint has cooled, trim away
the excess wires .
n
Plan so each joint is only soldered
once . Resoldered joints are messy and
more likely to fail .
