After a frankly
day at work, I wandered back to my shed to try and console myself that maybe, just maybe it was deflection coils and I will see some light on the screen. I placed the coils that John kindly provided and...I have a raster... of sorts!
.
I don't have the magnets or linearity sleeve back on the tube neck yet. Next is to refit these and try and pull the raster out to the whole screen.
