Does anyone know of a source for the 12 way Plessey connector for the rear panel socket SKT11 on the RA1217 receiver? Specifically it is the Free Plug Plessey Mk4 2CZ83302 / 5 with Accessory Set 508 / 1 / 03013 / 205. This carries all the audio and interfacing stuff for the world outside, and would be hard to replace with anything else. 73 and thanks, Dan ac6ao
