CTC-5 Westcott restoration

[SwizzyMan]

Not quite satisfied with the color temperature. While trying to do a proper temperature setup I ran into some difficulties. The manual says to turn the green and blue background controls 30% up from being at counter clockwise. And to turn the contrast control to the halfway position. I know what all this means but how could I tell where 30% is on the screen controls and where halfway on the contrast control is?

That looks great! It's inspired me to start my ctc9 very soon!

They are asking to set mechanically at a certain fraction of full travel (which should be somewhat less than a full circle max). So, just try the full mechanical range to see how far the control can turn and then set it an estimated halfway or 30% of the way as instructed. These are just starting points to get you somewhere with visible light on the screen.

When our shop entered the color market with the CTC-15, we went to 'RCA School' put on by the distributor, where we learned setup procedure from factory reps. They
had us do the whole procedure with both the blue and green Drives at max . Then as a final touchup, back either one (or both) down a bit to get desired 'temp'. The reps may have been "off the book" regarding the Drives, but that's the way we leart it and always did it.

Or, book procedures on earlier chassies may have been different.

In those screen shots of you CTC-5 running, it looks like the contrast is a mite low.

Did what you suggested old coot. Picture looks a lot better. Only problem is that the chroma hue drifts while the set warms up for 10 minutes then goes away but still very very slowly drifts. The contrast is no longer an issue here. The camera caused the bit of washed outness if you will.

Alright THIS is the finished product. I promise this time.

crank that color down its way over saturated.
I think it should be more like this

Tube color TVs are never "finished", as long as they can be powered on there is ALWAYS SOMETHING that you could say needs to be done if you look close enough...

That said Dave likes them a bit too pale, swizzy likes them a bit too saturated, and red is up a bit too high relative to the other primaries.
