not on the cyber 72 we shared, dave.
it was, in fact, a length of wire.
the 72 had one length, and the 76 had a shorter length.
(i guess you could call that a sort-of timing capacitor?)
i watched a cyber technician change the wires for the
purposes of doing a verification test.

On a vaguely related note, I found it amusing
that there was a well known hack for Cray's (or perhaps 6600's) which were
misbehaving: put a Tektronix scope probe on a test point that generally had one there
during final system checkout. The load (extremely mnimal by design) was just enough to
stabilize the system.
There was also the story about the major difference between a Cyber 72 and a Cyber 73 was
just a timing capacitor... Very expensive capacitor :-)
