Wanted. Plessey PV 213A Telegraph Signalling Current converter - Service/Operating manual
Really long shot, would anyone have a copy of the operating/Service manual for the PV213A converter?
I have downloaded the documents that the repository holds, for which much thanks to those that administer the service, but the EMER is more akin to an introduction to the equipment, and advises it should be read with the manufacturers documentation.
Any help gratefully received
