42-1003 -need advice
#3

De-soldering is as much of a process as is soldering. There are numerous tools, aids, that help. Flush cutting nippers are useful in biting off the the leads in terminals rather than attempting to bend the wire and possibly breaking a terminal. A plunger operated vacuum extractor helps a lot as well as de-soldering braid and forked hand tools. Adding new solder is very helpful before extraction as lowers the melt point of the joint. Following up with a scrub of isopropyl alcohol to remove excess rosin.

Much of the available replacement wire is PVC covered. Some brands have a tendency to shrink away from the terminal when soldered or worse, if a severe right angle bend is made in the wire, the conducted heat often causes the PVC to split and splay open. Many restorers are using textile braid covered PVC replica wire, the braid keeps the PVC intact during soldering.
