Sorry, I had my grids mixed up! I knew about the names though, just thought I'd mention that the CRT goes black (as B+ and boost decrease) when the width control is fully CCW. As to pin 4, the voltages vary between 190V with the width fully CW, and 151V with it fully CCW, again, no image on CRT. In the state with no image, B+ increases to 248V, compared to 236V with an image...I can 'turn the image on and off' with the width control for these tests.
These voltages on the HOT seem ok, certainly within range of the diagram, it's a weird fault. I'm not completely sure that my K networks are fully correct, but it would be strange to have my new ones and the original networks displaying the same fault, so I think it's something else.
Cheers,
Adam
