thats about the same current I I am getting.

one thing odd about mine, if I set the setup switch to serv, and adj the screen G2 for just being able to see the lines, I end up with a pretty dim pic(not bad just not as bright as some of my other roundies). I have a feeling the bias is off, I need to check the voltages at the cathodes.

I can of course increase the cathode bias to get a decently bright pic, but I have always read that is not the correct way to set it up, and that the bias pot should be fully CCW unless a gun can not produce a line, in which case you max that drive and then turn up the bias until it can produce a line.

IIRC my CRT tested fine, so I am back to thinking I must have something off in the overall bias of the CRT, esp considering I am at 25kv (even when fully loaded, it only drops a bit).
