Rear panel mike jack

[Dennis Egan]

I have a K3 with a rear panel mike jack and the rear panel Line Out jack
that have become intermittent.   I can find the Line Out jack on the
Elecraft website, but not the Mike input jack.  Are they the same part
number?  For that matter, are all those jacks the same part number?  And is
there a replacement that can be purchased from Mouser or other supplier?

Dennis, I had the same problem with the line out jack.  Spraying contact
cleaner on a plug and working it around didn't help; one channel was
open.  You need to replace the whole board unless you want a huge task. 
Find someone who has upgraded his K-3 to a K-3s.  He will probably have
the old board to give you.  It's the KIO3 I/O audio module.  Most likely
someone seeing this message can help.  Jim W6YA

Hi Dennis,

I replaced mine a few years back with Switchcraft jacks from Mouser.
Unfortunately, I can't find any record of which part(s) I used. Looking
at the Mouser site, I believe this is the Switchcraft series:

https://www.mouser.com/datasheet/2/393/35rapc__hn2_cd-475095.pdf

Just check dimensions to verify it's the right part and order the
correct pin configuration (mono, stereo, switched or unswitched).

Hope that helps.

73,
