first images of video..
NOTE,,
I have no brightness control yet, and I have not got IF input to work yet, this is video input direct.
and I'm seeing the same issues that I saw with 8yp4 that I saw on the Arvin, it just NOT seem to work well with cathode input, but loves G1 input.

I dread having to rig up something to hold the 24ahp4 tube, or the 21aup4a out of my SC again
