David,

These 3 capacitors are in the can.
They are each made up of several capacitors in series.
The values indeed are not publicized, but if I am not mistaken they are (ref. to the numbers in your schematic diagram):
C62 = 2.5nF-20kV
C63 = 5nF-10kV
C64 = 2.5nF-20kV

The 5nF capacitor is made of 4 capacitors in series; the 5nF has 8 capacitors in series. (All these capacitors are identical.)

I'm afraid this doesn't help you much further.
