Hi Don.
In my opinion, I cant see how it could be the yoke.
the flyback and the yoke are a tuned circuit, and peaked for the
highest voltage, or resonance.
more , or less inductance could only reduce the voltage.
check you B+ going into the flyback, maybe about 115 volts.
I am only guessing though, I havent seen this model set.
