Hi,
Working on a Hantarex, complete rebuild including the HVT and fired it up - seemed to work great then got some "interesting" displays,,,,,,,,

I am using a Wells Gardner pattern generator with the white grid pattern displayed.
It's about 6 min. long but you can see what I am talking about. Starts out great and then I get a background raster showing up, flashing and stuff. Around 2:30 it get interesting...... Eventually it settles down and goes back to normal. I think that it might be the CRT but I am not positive - looking for some insight.
I checked with my B&K and nothing bad shows up.
An interesting note, originally the colors were perfect but now, after some testing and such, the outside corners are off, like the yoke was moved but it is solid in place, with the white varnish that was applied at the factory intact, as is the varnish "line" over the ring set. Very weird......
Anyway, the point is that I am trying to figure out if the CRT is bad. Anybody else see this?
Thanks in advance
Jeff
