When I built my K3, I was not able to get a tight enough fit between the DSP board and the front panel to keep that thick washer (that goes over the phone jack) from rattling. I pulled the DSP board this morning to send in for the upgrade, and would like to fix the washer when I re-install it. Any tips, or am I making a molehill out of a flat plat? 73, Mike NF4L
