[R-390] replacing components

[wli]

Geee, this is all so complicated! I just carefully clip as much wire as possible near flush with the lug joint, including wire that was wrapped around the lug. Heat it up, and all of it falls off leaving a clean lug.

The new component's lead gets securely fastened mechanically by wrapping it 270-360 degrees around the lug, and a fresh solder joint completes the electrical connection.
