Can anyone ID this transformer?

[martin martin]

Here's some serious HV for everyone!  One of my clients gave me a '93 vintage  defibrillator   I am taking it apart for the green CRT among other things.

Deep inside I found this possible choke or transformer?

Also a serious 5 kV cap!

I suspect I can't really add anything but I have taken a few medical HV bits apart before and that kilovac looks to me like a high voltage relay / trigger tube and the transformer looks like a pulse transformer, usually for adding a spike of voltage to a pedestal / stored charge by being wired in series with a circuit. This spike usually then causes the stored charge to flow by forming an arc or triggering a tube...

I have a brand new  10 Kv 1200 pf capacitor, just took it out of it's package. Does anyone have a use for this. About 1 1/2 inch diameter and about 7 inches long.  Looks like it is a ceramic device.   one only.  Does anyone have a use for this thing ?
Thanks  Pharma Phil

Those things are useful for those of us who like to play with actual high voltage.  You know, like 10kV and up! 

That item is almost certainly a trigger device.  Looks like an SCR or something, marked 12V on the end with small coils in the clear plastic underneath is.  Those caps can start your heart, but they can also stop it!  It probably has an internal resistor or one across the terminals to discharge it when not in use.  The ones in microwave ovens have had them for some time.

This is not a time-limited real auction.  I take the " buy it now " to mean that he could not sell it by auction so is looking for a buyer willing to pay an outrageous amount for this item.

Yup, that's a crazy price.  Maybe if it was rated for 100kV...
