The equipment shown in the photo is not a CUJ Receiver, it's a 692 Transmitter.
The CUJ Receiver had a self contained power supply and only one tuning unit mounted to the left of the front panel.
I can clerley see in the photo a power supply mounted below the radio set and two tuning units, the one on the left is for tuning the trpler and the one on the right is for tuning the final RF output stage.
