Shows 420 pF on an LCD cap meter - Sprague Tel-Ohmike (at 600V) shows
220 pF. Cross-testing other (similar) caps shows a very small variation in
Someday when I'm rich I'll buy an ESR meter that goes down into the pFs
and that'll tell for sure - but the Tel-Ohmike is consistently within 4 or
5% of it's readings when using known-quantity devices, so I think the
doorknob needs a little Graphite....
