Believe the post was by me. Computer supply. Should be available in electrical supply too.Will need to use some solder wick to clean up the board after getting the pot removed. The solder comes in a small tube and is not very expensive as your only buying like half once. The digital iron was spendy but got on sale for like $45 from Radio Shack on sale. Well worth the $$. Was borrowing one all the time. Probably use it now every week to repair something. Hate wire nuts especially in outside applications(trailers).
Wire nutz and calcium chloride don't get along too well...lol
I use Western Union style mechanical (squeeze style splices) that come filled with di-electric grease, not to be confused with the dry, fold over and squeeze piercing style.
