Collins R390/URR HF Receiver

Technical data

The Collins R390/URR was made in the 50's.
The black enameled panel receiver may indicate that it is a CIA model.
Whatever, it is in a pristine nice state and has only needed a small realignment of the oscillators and HF head coils.
Some modules were cleaned together with the R391/URR ones.
