pins 1 and 3 of the phase detector should have the gated burst, and that seems to be what you have, so it's OK. Pin 2 should have the continuous wave at 3.58 MHz from the oscillator. The schematic says 10 volts p-p - the copy is not clear if there is any pulse waveform or beat note waveform superimposed or just pure sine wave.
Yes, it is possible the crystal is bad, but I was under the impression that when the crystal dies the oscillator stops in these sets, and you definitely have the oscillator running
