(K3) Assembly (again) Front head

Hi all

I had nearly finished assembly when I picked up the unit and heard a rattle, process of elimination I found it in the front head unit and its the flat washer between the phones socket and the front panel plate itself. Even with the knurled nut screwed on the front, the flat washer is still loose - is that right??

With everything done up e.g. the DSP board etc it doesn't push it all together enough.

Just want to see if this is how it should be?

The page in the guide is 41,

Thanks

Rich

Re: (K3) Assembly (again) Front head

I had the identical issue. After verifying that all other hardware was
correct and connectors mated fully, I added an additional thin lock
washer on the jack behind the panel to take up the space. I'm sure it
wasn't necessary, but the little gap bugged me.

Rick,

Apply some pressure between the board and the front panel metalwork -
Squeeze with thumb and fingers while tightening the knurled nut with the
other hand. Tighten until the washer is tight. That method will do no
harm.

I tried that first. In my case it resulted in what I considered an
unacceptable deformation of the front panel. Maybe I just had a bad
stackup of tolerances. YMMV!

I remember having the same problem when I built my K3 about four years ago.

It was never going to work without an additional washer which is what I
installed.

That's exactly what I experienced on #474 just after I built it. The washer
rattled. There were a few supportive posts here alluding to the same issue
at that time. However, Elecraft support said it was something obvious that
I had done incorrectly in construction. I went back and retraced all the
hardware assembly on my front panel and all was consistent with the manual.
Trying to tighten the knurled nut further with my fingers simply deformed
the front panel until I released the pressure. All the buttons and other
projections were equal in their distance from the front panel and were
visually "spot on". All functioned perfectly. I ended up putting a small
glob of hot glue on the washer to stop the noise. Slept better that night,
if nothing else.
