What's Wrong With This Set?

[peverett]

That raster is definitely due to the yoke being pulled back. I have an Admiral portable on the bench right now and the yoke is pulled back for servicing(and the raster(and picture) looks like that.

It is probably pulled back as the plastic that held the yoke in place has fallen to pieces with age. RCA's, Zeniths, and many other models are notorious for the yoke plastic falling apart. Their have been blogs on VideoKarma on how to make new ones. (I will need to do this for my Admiral also-the yoke plastic is a shrunken shell of what it originally was).
