We replaced this transformer 239111 with an original about 6 months ago and
now it is back with the same failure. I notice that a PTK195W in the shop
has a different transformer, 250694 which is marked 34kV. The one in the
PTK195M1 is marked 28kV! The two units use different CRTs but I find it
curious that the transformers are so different in rating and look. the
239111 is a lot smaller and cheesier looking. Do I have the numbers right?
The numbers on the transformers are different than the TCE part numbers,
which I get from Tritronics research.

Any ideas on why repeated failures of the IHVT six months apart with no
other symptoms noted? No coolant leaking on the anode leads or evidence of
arcing on this one.
