World's smallest color CRT

Hi,
Try reversing the horizontal deflection coil connections. That should change the scanning direction. Make sure the connections are isolated from The B+ and ground, that way you won't burn any thing out.

That *should* get the scan going in the proper direction so that the printed material will be correct, but the beam will be crossing the color stripes in the wrong sequence relative to the "index stripe" so the colors will likely be wrong. Perhaps rotating the tube 180 degrees in the yoke after swapping the horizontal deflection connections will restore the proper stripe indexing sequence.

Thanks for that.

There are two index stripes, green and UV, and there are two photodiodes to "read" them. Do you know which one reads the UV index emission? The amber or the black one?
