CTC-4 Chroma Alignment
I'm now at the point where I need to make sure the chroma section is in order, but I can't find any service info on how to get it done. I do have CTC-9 stuff from Sams, but the circuitry in the 4 is vastly different. Can I assume that I make the same kinds of tweaks to this one, same as the later chassis? Zero beating the local oscilator is an easy one, it's all the other transformers I won't be able to get right without some pointers.
For example, on the 9 it has me tweaking the local oscilator trans for max deflection on a DMM, so I assume the same is done for the driver trans (T115) on the 4? T115 seems to have a lot to do with the phase angle seen by the demods (big change in color bars), so do I just tweak for correct bars with the color and hue controls at center? What about the band pass and demod driver transformers?
