Quick question- are the plastic coils for the convergence supposed to run hot? I was trying to get some adjustments made, probably had the set running for an hour. Noticed the slightest amount of smoke coming from the area of the L601 convergence coil (for blue horizontal lines on the left side of screen). I shut the set off and found the surface to be 145F with an optical thermometer.

The coil below it, L603, was seized up, but it seems that the heat from operating has freed it up, so I guess that's nice.

I feel like I am at least making some headway, getting an idea for how the pots correspond with the grid on screen. Purity is out of whack now, so I have to circle back to that, but at least I'm a little less jumpy around this thing. Once every once in a while, I head an arc or two snap when powering the set on. I'm still trying to figure out where that could be. It's pretty quiet in operation. Actually, the CRT doesn't seem to whine like it used to when I put a grid or dot pattern on the display. Would a new tripler be why?

Also, how are these ECG triplers? Are the failure rates similar to original?
