While waiting for information on the convergence transformer data I decided to do the IF and chroma alignment. The video/chroma was pretty close as-is with just a little adjustment needed. The IF is a different story, however. It had a narrow peak instead of the double hump broadband response shown in the service data. I was having problems with the cores sticking in the IF transformers and I ended up twisting the coil form in the second IF can. I had to remove the transformer and get the cores out and do the surgery on the broken wires. As of this morning I have the repaired transformer installed but not connected. The third and fourth transformers will have to have the cans removed so I can remove the metal clips that engage the cores and try to get them back into their places.
The marker in the center of the scope screen is 44MHz.
The second shot is the chroma response to the demodulator input and is pretty close to what is called for in the service information.
