The cap is 1uF , 280V ac rating. From the .5*C*V*V that comes to 630V, so
something awry there.
No more than 250V m 60% of likely DC rating, and I would have thought more
like an equal split between 12V and 1800V so about 150V, transformers are
much the same size if that is anything to go by

If I ever get this thing working properly , how to check the average current
drain?
I am thinking 12V supply >- ammeter >- bank of 20V Cs summing to about 0.1F

that is a current limited 12V supply , not a car battery of course

It may appear counterintuitive, but a rating of 280VAC/630VDC for a
metallised polypropylene or polyester capacitor is not uncommon.

http://www.ibselectronics.com/pdf/pa/wima/wima_pulse_capacitors.pdf
http://www.descartes.com.tw/product/wima/wima_pdf/WIMA_MKP_4.pdf

See the Axial Metallized Polypropylene Capacitors on page 10 of the
first PDF.

In particular, there is a 1uF, 280VAC/630VDC cap, p/n ARPM10563KYUKZZ.

Is there any surface appearance hint? slight crazing/discolouration? would a
1000V / 1Gohm insulation tester show anything and is the conductive path in
the bulk or the surface? I've seen this problem with sockets going
conductive but that is due to arcing/localised heating and charring so
somewhat obvious

In general, or best recollection for my Sanyo, can you approximate the
typical locale of the numbers I'm looking for on the PCB? Maybe the
basic format in general? I see a few likely candidates.
