I'll say.Almost every monitor you're likely to come across will use a more modern 'Flyback' transformer (a.k.a. Line Output Transformer / 'LOPT').
Triplers are an older technology used mainly in televisions and I can't recall ever encountering any other monitors that use one other than the CUB.
The problem here is that authentic triplers for a CUB are getting rare and very expensive - there's a whole load which are electronically identical in different form factors or with different cable lengths. This problem with the arcing and rapid failure is definitely not normal - Triplers can break down internally and arc but it's a bit unusual to have them arcing to the point of burning through the plastic and jumping an air gap.
I was watching Retro Electro Workshop on UKTV recently and the main repairer, Rob Howard, has some ancient EHT test equipment.
A few of the 10 programs feature some of the interesting work that he's been doing, e.g. testing and repairing a 50's TV and fixing old tape loop players for Radio Caroline amongst other things.
Perhaps the particular Cub's that failed had a problem that caused the triplers to short out, possibly?
