Perhaps it is time for a new acronym/smiley/emoticon here on the forum: HBC
This is a
Head
Banger
Component, meaning that I will probably have to use the

the most important detail to ensure proper operation of this gizmo, so that one capacitor is definitely a HBC.
The missing connection is just ... I don't know what that is.
