I cannot explain it.
If it were not disconnected, there is the wavetrap. It attenuates 460kHz.
If you used good high levels of 460kHz and it does not show at he output, I would disconnect the filters and put the signal directly through them, trying to align them to it.
Keep the input is under the plate voltage, so if using a solid state generator, use a capacitor and a zener in parallel to the generator's output (i use it all the time, I described it a few years ago.)

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
