The "phantom tweeker": a past individual who had a passion for adjusting things which did not require adjusting. On the other hand it could be a bad tube or the coil adjustment drifted as it aged. Obviously my auto correct did not know what a "tweeker" was.

Nevertheless you should make the fine tuning test for the ghosts.

Most times I've heard it mentioned here it was under the name 'screwdriver drift'...

I'm glad I don't have auto correct sometimes....Someone on AK has the rather humorous signature line "Dear auto correct, I'm sick and tired of all your Shirt."

Before doing alignment, I would try subbing the IF tubes, beginning with the last one. But watch out for tweeters though.

Phantom Tweeker makes much more sense .

Adjusting the fine tuning does change the ghosting somewhat, and at one end of the control the ghosting is actually doubled up so the image is tripled. As I adjust the fine tuning I also have to adjust the picture control due to the changing signal level across the fine tuning range. I could post a video to show the behavior.

As per old_coot88's advice I am going to procure more 6AG6's to sub in for the IF tubes to see if that makes a change. I'm secretly hoping it wont as I eventually need to learn IF alignment and I may as well start with this set.
