[R-390] Re: R-391 restoration update

[Bill Smith]

Stating the obvious... use a temperature controlled soldering iron such as a
number of Weller models.  Tips can be obtained for a range of temperatures.
This is especially true when working with printed circuit boards, but holds
as well for point-to-point wiring.

Another hint, get a "Solder-Pullit" solder-sucker.  You can heat a
connection, remove the solder, then unwrap component leads and dress the new
parts as the set was originally constructed.  I have seen Chinese
knock-off's for $5.00, though I am sure they are products suffering patent
infringement.  Small versions are available at Radio Shack, but I prefer the
full sized devices.
