Thank you to all that replied. The resistance checks validate what Micheal reported.
My ringing tests on the primary indicate a lot of damping and not what Leo eluded in the posted pictures.
The ringing test on the feedback winding, indicate a much lower amplitude but the ringing is there.
The test were done with a 1000 Hz square wave with a duty cycle of 1% and an amplitude of 10 volts.
I have posted two scope pictures in the VE3FWF folder in the Photos section showing the results of these tests.
So I guess the HV transformer defective and the T922 becomes a parts mule ...
