I think you may be onto something there Alistair.

My attention has moved to the scan coils and Alistair's comment about the HKS transformer. I have just unbolted it and by rotating it by 90 degrees I can make a little change to the frame scan. I think I may need to consider mounting the transformer somewhere else.
Alistair, you are doubly a hero. Firstly for rescuing me with the isolating transformer when I found myself with an HKS CRT and secondly for correctly identifying my silly positioning of it on the chassis causing myself and many folks here and VRat hours of puzzlement.
I am very grateful to everyone but especially to you.
Very many thanks,
Peter
