Neil,
That is quite normal. The microphone jack pins are secured to the
board, but there is some "play" between the pins and the shell/housing
of the jack.
The two standoffs are used as spacers to maintain the proper distance
between the metalwork and the front panel board - and as you indicated,
to prevent board flexing when a mic plug is removed.
You can secure the mic jack shell by removing the left side panel and
scraping some of the solder mask off the board ground plane close to the
mic jack. Then with a large tipped soldering iron, heat the mic jack
shell and the ground plane until the mic jack shell will flow solder -
form a solder bridge between the shell and the ground plane. Grounding
the mic jack shell is a good step to reducing the possibility of RF
feedback, and should be done on all K2s with the KSB2 option installed.
