I'm Larin Parker for Expert Village! We're talking about the basic tools necessary for
maintaining and checking out audio gear that's misbehaving or perhaps is in need of service.
One possibility that you might need is you might need to re-solder some connections that
went bad. This is some what we call sixty forty solder, it's sixty percent ten and forty
percent lead I believe. You can also get lead free solders. Trick is the thinner it is usually
the better it is for working with small circuits. The thick stuff is more for wiring your house
and you want to make that when dealing with electronics you get flux core solder not acid
core solder. Flux core is for electronics, acid core is for plumbing. The do not work
in the opposite situation. Then here is just a portable soldering iron that I use. I recommend
going with a brand name on one of these, just the kind you plug into the wall and keeps
about thirty or forty watts on it is perfectly fine. Don't need to have the fancy features.
The really cheap ones for five bucks tend to break. I often find myself using alligator
clips these are very useful to diagnose which part of the circuit needs some help, you can
connect things up in different arrangements and reconnect things. Here I have my trusty
screwdriver which I'm going to use to open virtually everything and sometimes make some
adjustments of little parts. I recommend having both a flat head and the Phillips head, and
it's a good idea to have a number of different sizes. Finally you need some wire cutters
and some wire strippers. This will do both, cuts wire down at the joint right here, and
then in this little nick right here, I can cut the insulation only and pull the insulation
off of insulated wire so that I can re-solder it. Those are the basic tools that I use to
do my primary diagnostic and just basic cleaning and maintenance of these instruments.
