While performing the IF alignment on my K2 s/n 7809, I must have backed the
slug on L34 too far up against the can. Now the slug doesn't move when I turn it one way or the other (at some point I was able to advance it downward to the 1/2 way point). Is there any way to re-index the slug onto its threads so I can avoid replacing L34 and the desoldering that goes with it? Thanks.

Mark,
The only way I know of to do it reliably is to replace the inductor. I suspect you stripped the threads on the inside of the inductor core and not the slug. So just bite the bullet and replace the inductor. 73, Don W3FPR On 6/17/2018 11:41 AM, Mark Petrovic wrote: > While performing the IF alignment on my K2 s/n 7809, I must have backed the > slug on L34 too far up against the can.

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.
