Hi.
After two days more work it was time for a test.
Unfortunately I don't have the 10 inch Cossor tube.
Although I have access to a 9 inch Mullard CRT I was uneasy about using this for tests. The mounting angle would need to be correct to inhibit any stress on the glass and if I had to move the chassis to make adjustments or take voltages I didn't want to go round that particular route.
So I thought of using the MW6-2 again like I did in the Pye B16T. So I cobbled it all up only to find an issue with its scan coils with smoke being the result. So I then just sat the MW6-2 on the chassis with the Cossor scan coils but no focus coil. This actually worked and hidden in the blur you can see the frame and line lock up and there is a picture. I discovered the brightness control was faulty which I need to replace. Tomorrow I'll try and add the MW6-2 focus coil and see if I can resolve a better picture.
