My Brand New CTC-7!

[SwizzyMan]

Ok got the intermittent signal issue fixed by cleaning the tuner tube pins. The signal is now there but still not all that great in picture quality I'm hoping it just needs a focus adjust. The horizontal hold loses sync about a minute after I adjust it correctly. Here are the screen pictures scroll down to the end of the page. http://imgur.com/a/oTaRJ

loss of horz after a min, I would try subbing a new horz osc tube 1st then try a new sync separater tube. Is the horz hold critical when setting?

Don't worry about how it looks at this point you have to work the problems one at a time.

Was the horz hold always unstable? if not what has changed since it was stable.

Always unstable before and after I recapped. I will replace the tube and get back to you in a few mins.

is it critical in adjustment? you should be able to turn it at least 1/2 turn either way after it locks, and it will still hold OR do you have a very narrow range turning a few degrees either way will cause it to flop.

does it flop both ways or only one?

[SwizzyMan]

Ok put in a new 6CG7 and that helped still bends but it is not very noticeable. It will flop both ways I still dont have too much turning room before it loses sync. Please note this 6CG7 came out of an rca portable but tested ok.

[DaveWM]

how much adj do you have is it at least 1/2 a turn, I am asking this for a reason
.

[DaveWM]

and what is "bends" I don't understand what that means. a video is needed for "bends"

[SwizzyMan]

Yes a 1/2 turn but it bends a little bit more at the half turn both ways. Good thing is when I turn it on it syncs from startup unlike before where I had to adjust it every time I turned it on.

The image visually bends in places or twerks.

I'll upload a video now

Here is a video of what I currently have. https://www.youtube.com/watch?v=kQTEzw2FgCA

turn the brightness down
adj height and lin
then grayscale setup.


I don't see any problems other than maybe fine tuning issues.

[SwizzyMan]

Hmm well now I dont have a clear audio signal... The picture is fine this happened after I wiggled some tubes to make sure everything was seated. The audio is static and the sound input is at a higher pitch sound. I will still do what you told me to do though.

[SwizzyMan]

Ok now the hold isnt great ugh.

[DaveWM]

what does it mean hold is not great, is it critical, does it do it on all signals or just the generator

Its hard to remotely diagonose an issue unless you either post up videos OR give very detailed descriptions of the problem.

IF for example its critical (very narrow range of horz hold with flopping both ways on either side of hold, then I would look to the resistor that is across the hold coil as maybe going high in value. If it just loses sync and is not critical then I would think its the horz osc or the sync sep (but can be readjusted and be not critical again).

Maybe another poster can step in for a while and offer some other insight based on what you are describing.
