First Restoration - 50s RCA 14PD8055

Just got my first TV restoration running after a full recap and some resistor replacements.... a little knob twiddling and things looked great, with good brightness and contrast. I have a couple questions I thought someone here might be able to help with:

1) horizontal width is too wide even after using all the adjustment. To compensate for squatty images , height must be over set resulting in loss of the extreme edges of the field. I checked anode voltage and it was fine at 14.5kv. How should I approach correction? UPDATE: Current in horizontal output cathode is about 30% higher than SAMs spec and I do hear some fizzling that might be coming from horizontal output transformer... I noticed wax was pretty soft and warm after shutdown..normal???

2) there is some visible (but very tiny) continuous arcing going on inside the neck of the CRT within some glass rods. Is this normal and will it hurt anything over time?

3) I haven't done an alignment. If I am getting good reception, will I have much to gain? I have been accumulating lots of test gear (all vintage tube) and restoring to good working condition, but what is really going to be needed for TV alignment? I have Tek 545a, HP606a, Measurements 80, old Hickok sweep generator, vtvms, TV2a, etc. I am unclear about the "marking" signals referenced in the Sams to do the alignment.

I hope these questions aren't too stupid... I am a newbie to this and really to any formal electronics training beyond my USAF experience in the early 70s. Been devouring old tube reference materials and that has really helped. This is FUN (most of the time)! I am a nostalgia nut and love just about anything with tubes. I have a dual chassis Admiral TV from 1948 and that "cool Zenith" mentioned on the forum waiting on me next, along with some radios.

Thanks,

Dan
