Without wishing to add to the complexity of this continually evolving thread, there is going to be some difference in signal voltages at your planned line selector switch.
The output from the WXAD10 is liable to be much more than the 250mV (or probably less) from whatever stereo cartridge you use in the yet-to-be-fixed Garrard. This might mean some attenuation may be needed for the new device.
