Well my franken-chancellor is alive for Halloween.

So I changed all the ceramic Elmenco caps in the vertical and the weird non-linearity persists. I'm going to check vertical tubes and look at the couplates and lytics in the vertical next.
Anyone else have an issue where the yoke centering rings move but don't seem to have any effect?
I also cleaned up the HV cage too. I decided to silicone the mouse chew on 2 of the wires. And I installed a solid state focus rectifier (the original Zenith focus tube was dead) leaving the original tube to act as a decoration.
