Hi Peter,
How did you degauss the scanning coils? I remember the method used to degauss the Pye LV20 scan coils was to apply the rather brutish method of hitting the coils with a burst of HT. Bangs and sparks but it solved the problem. An alternative method is to use a fully charged capacitor.
Sound on vision and vision on sound is often caused by the RF deck HT supply decoupling capacitor having gone low capacity. The 16mfd capacitor is located on the main chassis near the five pin socket.
