Hi PlatinumBird55,
Yes, a chunk of wax is missing. I would be very careful about RTV. The "vehicle" for many RTVs is acetic acid (hence the vinegar smell as it cures). Acetic acid is conductive. This Flyback likely develops about 16KV give or take. You must find a product that is HV rated and follow the instructions. HV rated Glyptol may not hurt but may not help. I don't think that the issue is arcing between windings as much as it is arcing from the outer ring (highest voltage) to nearby components. If you fire it up without doing anything to the flyback, do it on a dry day.
Definitely remove, inspect and clean the HV Rectifier cup.
The more antique radios and TVs I service, the more I should take before / after pics of parts after cleaning off the tar / nicotine from them, and use as a public service announcement against smoking.
