george I have not messed with consumer stuff very much, but I believe
the so-called triplers in TV sets disappeared quite some time ago. That
thar critter appears to me to be an integrated high voltage
transformer, (aka flyback transformer, aka FBT) The part/sub-part
(whatever) you are calling a tripler is, I believe, actually a divider
network. Note the 2 variable resistors, screen and focus. I doubt it is
bad.

The flyback transformer is soldered to the circuit board. There's another
part screwed to a plastic bracket connected to the flyback by a thick
cable. According to the schematic it's a tripler.
