If you are measuring anywhere near 30K across a coil then it is most likely open. You should be reading less than 100 ohms across any of the RF coils, and around 10 ohms across the oscillator coil.
It still seems your oscillator is not working. The 24A performs both the functions of the mixer and oscillator. It can still be passing the 175 kHz IF signal but not oscillating. If you can hear the 175 kHz IF freq at the 24A grid, then everything is good after the mixer, but you have no oscillator to mix the received signal with to produce the IF freq.
What you are probably hearing is the feedthrough of the 175 kHz IF freq into the mixer grid if you hear the same signal regardless of the position of the tuning dial.
