This biggest single contributor to the horizontal scanning frequency
noise came for a poorly constructed flyback transformer.


Flashback memory time. I don't know *how* many TV sets, mine and friends,
that I kept alive for a while longer by painting the flyback transformer
with that red, high voltage "Klyptol" stuff. It usually stopped the
hissing and squealing for a while but eventually the transformer would
carbon track to ground.

I also would *like* to forget how many of those TV sets threw me on my
rear because the high voltage section wasn't discharged.

When you think about it, all this new, low voltage computerized stuff is
kinda boring. No challenge at all.

In deflection circuits I designed the FBT had a bleeder resistor, to improve
regulation and discharge the CRT.
