The panel designs I'm working on won't be that cramped. They'll have
the same jack size and spacing as MOTM. The space savings will come
from using smaller knobs.
I measured the vertical distance from the top mounting hole to the
center of the first pot on the Encore UEG. Assuming I use a similarly
small diameter pot, it turns out that I can fit eight rows of panel
parts, spaced 1-inch apart, in the 5U high panel. The horizontal
spacing is 7/8-inch. In other words it is the MOTM jack grid extended
all the way to the top. I realized today that I can fit two CGS Slope
Detector modules into a 1U panel with this approach.
