Hi Nick,
Thanks for your help
It was indeed a short in V15, to prove a point I swapped the pair again and switched on. The new 1.1k resistor went o/c instantly.
I haven't checked the transformer properly yet but will report back on this along with the other voltages. I don't have a scope sadly.
Is it likely that the frame transformer is now scrap? When it worked briefly there was a distorted raster but interestingly had a horizontal line on the screen also.
