Hi

Do not use silver bearing solder It is no longer recommended by Elecraft.=
 The reason silver is alloyed with solder is to prevent the solder from d=
issolving the silver coating from surface mount components. If the solder=
 is already saturated with silver then it will not attack the silvering o=
n the surface mounts component. There are no surface mount components in =
any Elecraft kits so you are just making it hard on yourself if you use i=
t. Use a good quality 63/37 .030 rosin flux solder like Multicore or Kest=
er 44

Most paste flux compounds have a corrosive base don't use them anywhere i=
n your kit unless you know for sure it is only rosin base. The crystal ca=
ses do not require any additional flux. The Radio Shack stuff is corrosiv=
e

The solder blob method is the accepted method to strip the toroid leads. =
Learn to do it right and you will save yourself a lot of troubleshooting

All of the above is just my opinion but it works for me

13)" TORCH" TYPE butane cigarette lighter and fine grit sand paper for
striping enamel wire. There are several ways to do this but this method
works best for me.
