Raytheon/Sonotone flyback

[Gus1969]

Hello again. This project is mine. I have a lot of appreciation for this television model, because my grandmother had one just like it, and it was the first television that I destroyed, trying to repair it. I was 17 years old. Fireworks included for the same price...
I never knew what happened. I think I bypassed all the fuses and it worked for a few hours, then smoke, boom and a new color TV gift from my Dad.
Obviously it is an american kit and I don't know who its original manufacturer is. My grandmother bought it around 1965.
The CRT is original Raytheon. The flyback is in bad condition. For years I repaired solid state flybacks with silicone. What is the best way to proceed in this case? In a hot oven and fix the wax? What kind of wax? I'm worried about the humidity inside. Thank you so much.
