Page 34 of the manual in the link below shows the circuit for a Sony TC-640a tape recorder, the question is what is the function of Q704 and Q705 in the system control/power supply section? I'm ok with the rest of the circuit in that section.
The circuit for the TC640 appears to be the same except that those transistors and their circuit aren't fitted.
I might be suffering from wood for the trees on this one:
