I replaced the candohm resistors with chassis mount power resistors. Although the originals in this chassis were OK, there were failures in the other two I've worked on. So I figure it's best to replace them.



Also got the replacement focus control installed. Those big 100 ohm resistors barely even get warm.



Did a little touch up on the alignment and the sync is even better now. Sound much better too. One of the slots in the thread shafts for the sound IF was spread apart like a screwdriver had been jammed in it. Seems likely someone had tried to improve the sound in the distant past so I wasn't surprised that it needed adjusting.

I also cleaned and lubed the tuner. I'm calling this one done which leaves fixing up the tuner on the other. I'll be glad to get these beasts off my workbench!
