Quoted from jeffc:
Has anyone researched/confirmed if Williams chimes were designed properly with respect to this node spacing?
I really doubt it, and probably why it sounds as bad as it does. The spacing for the mounting points are all the same for each bar in the Williams unit and the result is what I described a few posts back as far as the quality of sound goes. It might seem like they found one bar the worked (middle bar) then added a shorter bar and a longer bar to add variety (at the cost of purity) of the sounds.
Compared to even the most basic of glockenspiels, the mounting points are different from bar to bar, to produce a more tuned and refined tone.
In which, as you can see, the Gottlieb unit emulates, making for nicer tonal qualities.
Also, the striking point of the Williams unit is at the end of the bar, as opposed to the center of the bar. I would think you would get better sound quality by moving the placement of the solenoids. Again, I doubt there was a lot of thought put into the Williams' chime units.
