IIRC boost diodes didnt test like a common diode ? I do remember
they rarely went bad.

With the virtual extinction of 60Hz linear power supplies most new rectifier diodes can handle at least horizontal rate switching. Even the humble 1n4007 is found in switch mode supplies these days. I've used many normal silicon rectifiers as boost and convergence doide replacements in tube sets had good results. The original boost and convergence diodes were selenium for fast switching...If they had the modern fast switching silicon diodes we had now back then they would have used them instead of seleniums.
Still it is not a.bad idea to convert switching time to seconds then take the inverse to get frequency and make sure that frequency is higher than that of the waveform applied.
