Suggestions.- 1.- you remove the flyback and the hot, you connect a 680 ohms 20w resistor or a 75w bulb from the b + to ground and you touch how much you have of b +. Under these conditions the source has to be stable. This allows you to be sure about the regulation of the source.- - 2.- Connect your frequency meter at the base of the hot and check the frequency 15750 cycles.- Greetings.

Voltage has to be 103v, you don't have cut FR 401, you have diagram.

Good, put a load focus horizontally to see if it keeps the source or low also with focus, horizontal transistor is fine .. there is something you consume in secondary if you have that voltage.
