Never heard of heatsinks for micas either.
On most of theses electrostatic deflection sets (ones that use 7JP4's and the like) there are several high value 1/2w resistors connected to the HV/focus control. They are always way out of spec. Cause poor focus issues. duh
The 6kv defection caps should be replaced with mylar caps. You may be able to find ceramic disk caps but they tend to drift in value (heat up) do to the presents of rf energy and cause issues.
Looks like it's coming along nicely!
