Oh, I thought you subbed a different tube due to high cost.

So, finally it only was the horizontal Hold that made the fuzzy picture, everything works now. I redid convergence, and now it got a good picture! I am still not 100% blown away by it as much as I thought I would be, but its definitly is a drastic improvement from where I began.

Now, there are the small issues of : Jail bar, and of course getting rid of that pesky macrovision buzz and color lines! Anyone knows a good macrovision filter? I bet this could get handy with pretty much all the sets made before 1980 or something...?

I did, but the subs where also marked as alternative right in the back cover of the TV. By the way, what would be the effect of replacing an 6LX6 by a 6LF6 other than it would have cost me twice as much haha?

The sub makes no difference. IIRC all Zenith came with a
6LX6 or 26LX6 on series sets. Only other sets I recall were
Motorola hybrids came 6LF6 or 20LF6. Others probably used it.
I dont remember on Motorola but Zenith can sub 20LF6 for
26LX6.

Price difference probably due to most hoz outputs are used by
hams for amplifiers One tube probably has specs that are better
so more demand.
