Leo,
I see that you took the x-former in your pictures apart. Did you ever
determine what the internal failure mode was?
General comment. As Leo's pictures show, transformer failures can be
tough to diagnose since they frequently still have an output but just not
the correct output. And if you don't know exactly what the output waveform
is supposed to look like, or how long the output signal is supposed to
ring, then you could overlook the failure. This type of mis-diagnoses was
common when automobiles were still using a Kettering ignition system.

Hi,
You could try a lower frequency, like 10Hz or so, with a longer 'On' time,
to allow the ringing to dampen by itself.
Now it could be stopped by the short 'on' time of the 1% of the 1kHz.
Did you see ringing nicely going down like in one of these pictures?

This was a bad HV transformer en a good one for a 2235, but the principal
is the same.
Good luck,
Leo
