The TS-930 was assumed to be installed SO-1, the 20 MHz TCXO with 12V operation. The manual indicates all of components should be removed before SO-1 insertion, but the current OCXO "unit" cannot be fitted to SO-1 foot print. So just,

One terminal of R146 detached in order to cut off DC voltage source for the original crystal oscillator, and one terminal of C19 is detached to disconnect the output of the oscillator to the whole unit. If OCXO fails, just recover these two component as once is enough to be back to the original state.

Also the micro connector is added for the clock injection.

So as a result, the signal from OCXO can be injected through this smart connector, and also it's very easy to recover to the original circuit.
