The octal crystals in the transmitters were not used to directly control the transmitter frequency. They were marker crystals and in conjunction with the 1629 magic eye tubes would indicate when the transmitter VFO was tuned to a specific frequency. 
A number of the receiver were crystal controlled but did not use octal based crystals. Two crytsals could be pluged in to wherre the FT-230 was installed on the front panel.
