2. The power transformer has failed. The HV winding is bad.

3. If the power transformer has not failed, it will fail soon.

When the transformer on my precious Goldstar oscilloscope failed and no
exact
replacement was available (what a surprise!), I was faced with hanging two
or
three transformers externally. . . . .or rewind. Bit the bullet and
patiently unwrapped
and rewound the failed one. Five windings with three different size wire.
Miserable job,
but it did finally fit in it's case and except for a little hummummmumm,
seems to work
Ok.

The Heathkit ones usually lose the HV winding which is teeny tiny wire and
a real pain to work with, BUT the good news is that it's the outside winding
so you only have to unwrap that instead of all the whole thing. I suspect
the worst quality magnet wire available today is better than the stuff
Heathkit used by a long shot.
