K1 Filter Board

I have finished mounting all parts on the filter board, except the inductors and plugs. I was surprised by how badly some of the capacitors fit in the holes. It is not quite what I am used to from Elecraft but it’s really no big deal. Maybe the capacitors don’t fit because the original ones have been replaced with better ones.

Here is a picture  of my progress:
