[Elecraft] K2 L34 variable inductor screw repair

[Mark Petrovic]

Thank you, Don.  I just finished the replacement.  I absolutely dread desoldering, but it gave me an opportunity to use the $25 desoldering iron with an in-line solder-sucker I had in reserve. I removed the solder from the pins, flush-cut the pins on the solder-side, and solder-sucked a coupke more times. I then gently rocked the part side to side on the component side of the board until it broke free.
