The Sony CRF 230 Radio Receiver

A nice example of a Sony CRF 230 receiver reached me, following the death of a distant relative who had previously owned it. When I started searching the web for information on this receiver, I quickly found several references to people looking for copies of the service manual, which was no longer available. As my receiver was accompanied by an original service manual, I decided to scan it in and make it available to others who might require a copy.

Please note - the pages of the manual are "Letter" size (216 x 279mm); this means that they will not print out at full size on A4 (210 x 297mm) paper.
The front cover of this service manual states that it relates to models with serial number 30001 and later. I do not have any information on differences from other versions of this model, nor on differences from the later CRF 230B.
