Well, I've spent time over the last couple weeks on this set and got basically nowhere. This morning I got up at about 3:30 AM after falling asleep at about 8:30 PM last night, I had a full head of steam and decided to tackle this set, do or die.
I disasembled and tested everything in the entire horizontal circuit, found one missing cap on the width coil (this set was pretty botched up before I got it), and no change. After testing about a dozen resistors and replacing a couple that were way out of tolerance, still no change.
Then I noticed a couple green spots of corrosion on the back side of the width coil, where I couldn't have seen them before. Looks like a couple turns are shorted....which would explain why the turning the width coil does absolutely nothing. That, and the fact that the horizontal lin coil, which sits right below it, was corroded and open, leads me to believe I need a width coil. Spec on the Sams is .1 ohms, this one reads about 1.3 ohms.
I'll pick this up after I get one......
