I wonder if a vacuum tube damper diode could substitute here. Assuming that there's room enough in the area of the chassis to mount a tube socket and the tube where there's enough ventalation and a source of heater power. However, the period of time it takes the tube to warm up means no damper diode action for around 15 seconds, and the horizontal deflection circuits may not like that...
Forget that, maybe a SS damper diode from a CRT computer monitor would do it.
