How would one know when a pulse cap has pulsed out? Is there any indication?
Would it still give good readings? Or is it just a matter observing its
behavior in its normal operation?

In regards to this cap:

I too have seen that particular capacitor on Ebay (and the guy has
alot - I emailed him!).  To better determine what it is and if it's
any good, I emailed the people at CSI and this is what they said:

******************
Dear Andy,

	The correct part number is 25W064TN.  It has a dielectric
system of paper and mylar with hard foil electrodes and is
impregnated in a synthetic dielectric fluid.  It is generally used in
light duty pulse application.  See our web site, CSICapacitor-dot-com,
there is a catalogue page showing that part number.  The life will
be fairly short at rated voltage, approximately 10,000 charge
discharge cycles.  Thanks for your interest.

Any comments?  Suitability for TCs?

I hope this helps!
