OK, before any of you give me the "google is your friend" line cut me some
slack. I looked.
What I can tell is that people have asked but never really got any good
answers. There has to be some one in this group thats an old TV guy that can
lend a hand (cough... Art).
I replaced the tube on a 6100 and I cant get the convergence good enough for
me to be happy with it. OK, OK... My problem MAY be that I'm using a regular
tube (90 degree) but my god, this thing has BEAUTIFUL color and is razor
sharp. I dont want to have to go and find a 20+ year old tube with screen
burn, you cant make me! Yeah, the yoke has to be back a little more then
normal but my purity is good so thats not an issue. Also, I read that if you
use a 90 degree tube you'll get insane pin cushioning. Not here. I wonder if
it has something to do with the ZVG on my test bench? I've read the color
raster and color XY manuals and they make it seem like convergence is a no
I also have an Amplifone thats got a burn spot like I've never seen before.
Its about the size of the tip of the average ring finger. I cant wait to see
the dead spot on that one. So, I emailed a company that has the cross
reference listed on their site for $89.00. I think thats going to be well
worth it since I'm going to be spending $250.00 on it for a HV transformer.
Bottom line is that I am going to have to replace this tube so I NEED to
know how to get the convergence right.
In the 20+ years I've been doing this I have yet to get convergence right.
Granted, I've only tried a few times but still...
Anyone have any pointers???
