Jack, you know it was worth it. it saved another roundie from extinction.

hell im so happy that it works, i could pay you more money for that tube! lol.

Here is a pic of a time warner color bar, turn to channel 80 something youll see the same bar, and youll see the impurities im talking about:

as you see some of the color bars, you can tell the color circuitry is overloading, and the color control dont make much difference at all, but almost take all the color out, some scenes, there aint no color

Ya might try squirtin some contact cleaner in your controls. That might help some. Have you changed any capacitors as of yet?

nope. which could explain alot of things.


I havent even looked under the chassis thoroughly yet. LOL.

the only cap i replaced was a lytic in the vert circuit. which restored the picture.

it works very well for its age.

I got the purity fixed!!


I hooked in a modern degausser circuit that solved the problem.

When I wrapped the coil around the inside of the tube, and degaussed it, the impurity and convergence got all wacked out.

I just turned the purity magnet, it returned to normal!! im thinking that pure spot wasnt pure at all. it was magnatized, and the purity ring made that magnatized spot look normal.

But its all better now

now, i have to do a total reconvergence.

Yeah, if you jack with one, ya end up having to jack with the other. In any case, you're making progress... and that's what counts!

the AGC/sync is getting worse and worse as the set plays.

First, the horizontal wouldnt lock. now, its starting to loose its vertical in spots.

If i go back to the color bar screen, like I had it before, now the vertical wont lock, and the horizontal is tearing. the hue is awful now.

I can get the vertical to stop rolling, but the picture is half and half with lines if I do that.

Any ideas? im starting to suspect the 6BA11, but I dont have that tube either. But I really need to check all the resistors and replace the caps in the AGC/Sync area. im definatly showing progressing trouble in the area.

Need to start changing caps, Bubba. The lytics are tired and starting to fade out fast. I know it ain't as easy as changing that tube, but, it's probably what you need. Even if you got everything straightened out today by swapping tubes, those old capacitors in there will die out soon as you keep running it.

Hehe! I think someone in this forum is gonna be jelous! the arche-Watcher!

looks much better in person.

I found a 10meg-ohm resistor in the AGC/sync circuit that was reading over 22megohm. Replaced it, it improved alot, but not all the way, since the caps need changed.
