Ready to begin on my roundie

[rca2000]

I must say, I am IMPRESSED!!

That old tube has some REAL life left in it, as I thought it did. Boy, mike, you have made some serious progress on that set!! I guess it was worth it for me, to drag that old Admiral tv, with that old CRT, home with me, from that barn in northern Michagan, last summer.I ALMOST didn't, as I had an RCA , just the CRT, ready to bring home, but, just as I was ready to load it, it fell off the two-wheeler, and broke the neck. So, as darkness was approaching, I grabbed that Admiral,took it home, and removed the chasis and CRT, later that week. (I still have that chassis. It is a '63, or so admiral chassis, with the HV cage, on the opposite side, from the power supply.).

Mike,

I think the color bands you were speaking of is means you need a new 6KT8. As KC8 was saying earlier, it's like 6GH8's in RCA. They give the same problem, and always new replacing.

The color bands may come and go as you described... depending on the program, scene, or channel you are watchin. When I got my ctc15 pieced together a few months back, it had the same problem, but only on one channel. The other channels were fine. Changed the 6GH8 (6KT8 in your Zenith) and the bands went away.

You're gettin a pretty good picture there.

I probably need all 3 new 6KT8s. I stuck a 6AW8 in there, and it works perfect in place of a 6KT8, even though its twice its size. That means I need 3 6KT8s

anyway, i thought it was AGC, because the service info I have says that AGC setting control not being right, or if the AGC drive is weak itll do that.

I have to turn the control all the way to the extreme clockwise to get any kind of watchable picture. The same with teh color killer control. I have to turn it all the way over just to get a decent color picture. if i turn it back, even just a hair, itll go back to black and white. and its hard to explain, but when the color is on, you can see the interlace real badly than on black and white, but on the impure part of the tube, you cant see the pic because the interleave is so bad. When I turn the color killer on, it looks fine.

The only time is does it, is when it plays a modern show. If i go to an old happy days show, or any other color program made in those days, it looks fine, something is overloading the color circuit.

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
