With an RCA CTC15 I get 008.4
I measured again on this chassis and the meter is bouncing from 007.8 to 8.0

Just looked back, and yes I must have made a typo... But assume it's normal then.. So I don't know what to do next..

my mistake you can leave the 100k resistor in place to check ohms. if you look at the flyback it appears the wax is running out of the ends of the primary coil but typically it would run out of the middle of the donut. but there is nothing wrong with ruling out a bad fly or not. but just comparing ohms on the flyback if close rules out a bad primary but not the secondary since hv leaks in the donut takes that part out.

The flyback got toasted in this set.. We replaced with timmys flyback and I've got HV...

I received my tube order for this set.. I still haven't replaced the electrolytic cap on the sweep board.. But there is a vertical bar of about an inch or two on the top and bottom of the screen, and if I adjust the width to fill the screen, it just stretches the images.. With my Leader pattern generator I can get a round circle with the screen not fully blown up, but with it blown up I get an oval shape.. I did check all the resistors that are 1.5meg and up in the vertical circuit and they seem to be in reasonable spec.. The sharpness and contrast controls do nothing.. And it appears to be too much contrast on the screen that I can't adjust.. I measured the sharpness pot and it measures something like 3 ohms and it doesn't change as I adjust the pot.. The contrast pot, however does seem to be fine and the ohms does go up/down as I adjust the pot...

Look for tin whiskers shorting the sharpness pot.

None of the pots seem to have that issue, I sprayed them with contact cleaner too.. Also there is a slight hum in the speaker, when volume turned down, it's noticeable... Almost all tubes were bad in the audio circuit, and with the bad tubes, seem like the hum was a bit more louder at times at times, I was able to hear change in the noise as if there was a short, now seems to be steady with the new tubes.. There was very little color with the bad tubes in the color circuit, now with the good tubes installed the color can be turned up so much that everything just blurs out.. But it also has problems with the color, very noisy picture and the more intense the color is, the more worse it gets, color all the way down to a B/W picture, the noise is gone.. I know all CRT TVS have this and usually can be minimized by tuning it the set, but this just can't it's pretty bad.. Here's a video to show it.. There's multiple issues, but would like to start with the color issue first than work my way to the rest of them.. As you can see who ever put this rebuilt crt in didn't put it in correctly as you can see the numbers in the phosphor and then which you call it thing that should be down under the bezel, but I noticed the anode connector on the back is about in the same spot as any other tv, so turning the crt would only turn the anode connect more of a downward position, but perhaps maybe I could turn the tube around to where the upper part of the bezel hides that and the anode connector will be on the same side of the HV cage?..

needs a good setup,
HV set, degauss CRT, rough center converge,purity setup,full converge center/dynamic,grey scale. then take a look at it. worminess looks like fine tuning. focus poor do to convergence.

oh ok thats great hv is always a good thing, you got 23.5 kv on the anode and about 190ma on the coil ? if you got that then it looks like your in business now.
Linear Mode
