The focus coil leads were deteriorating so I reinforced them with heatshrink tubing.
The horizontal yoke leads were even worse. Basically everything to do with the horizontal on this set has been mutilated
So I threaded some new cloth covered wires up into the yoke. I also found that the two 560 ohm resistors were 760 and 810 and replaced them.
Now, I could finally rebuild that plug. I was able to polish off most of the gunk from the metal shroud.
I'm going to try another power up tonight.
